    VAR-200312-0352

    Vulnerability from variot - Updated: 2023-12-18 13:45

    Aladdin Knowlege Systems eSafe Gateway 3.5.126.0 does not check the entire stream of Content Vectoring Protocol (CVP) data, which allows remote attackers to bypass virus protection. It has been reported that under some circumstances, eSafe Gateway does not properly scan messages in transit. This problem occurs when data is passed to eSafe via a Check Point OPSEC CVP compliant firewall. Because of this, malicious code may be able to circumvent the filters imposed by the software and enter, or exit the network. This could lead to further compromise of network resources. A remote attacker can exploit this vulnerability to bypass virus filtering. When Checkpoint installed with Feature Pack 3 receives more than 2M files, the scanning program will be unstable during CVP inspection. For example, if the SMTP message exceeds 2MB, FW-1 will perform the following operations: 1. Put the information into the buffer pool. 2. Send data to the CVP server. 3. It will stop when sending 1MB or nearly 2MB of data. 4. Sending will resume after 5 minutes. 5. The CVP server allows data to be placed in spool\d_resend and enters a loop operation until the information is marked as expired

    VAR-200912-0424

    Vulnerability from variot - Updated: 2023-12-18 12:11

    Multiple clientless SSL VPN products that run in web browsers, including Stonesoft StoneGate; Cisco ASA; SonicWALL E-Class SSL VPN and SonicWALL SSL VPN; SafeNet SecureWire Access Gateway; Juniper Networks Secure Access; Nortel CallPilot; Citrix Access Gateway; and other products, when running in configurations that do not restrict access to the same domain as the VPN, retrieve the content of remote URLs from one domain and rewrite them so they originate from the VPN's domain, which violates the same origin policy and allows remote attackers to conduct cross-site scripting attacks, read cookies that originated from other domains, access the Web VPN session to gain access to internal resources, perform key logging, and conduct other attacks. NOTE: it could be argued that this is a fundamental design problem in any clientless VPN solution, as opposed to a commonly-introduced error that can be fixed in separate implementations. Therefore a single CVE has been assigned for all products that have this design. An attacker could use these devices to bypass authentication or conduct other web-based attacks. plural SSL VPN (Web VPN) There is a problem with the product that can bypass the security mechanism of the web browser. SL VPN (Web VPN) Network resources within an organization using a web browser ( Web server, mail server, etc. ) It is a product to provide a safe access method. SSL VPN (Web VPN) The product rewrites content as necessary as a proxy between the web browser and the server. SSL VPN (Web VPN) Web browser security mechanisms by accessing crafted web pages through (Same Origin Policy) May be bypassed. SSL VPN (Web VPN) Products that implement may be affected by this vulnerability.When a user views a specially crafted page, a remote third party VPN Or hijacking your session SSL VPN (Web VPN) There is a possibility that the content accessed through the site may be viewed or altered. Attackers may exploit this issue to violate the same-origin policy to obtain VPN session tokens, read or modify cookie-based authentication credentials, or perform unauthorized actions with the privileges of the web-based VPN domain. Other attacks may also be possible. Clientless SSL VPN products from Cisco, Juniper Networks, and SonicWall are vulnerable. Other vendors' products may also be affected. We will update this BID as more information emerges. 2. Web VPN authenticates the user and assigns an ID to the session, which is sent to the user's browser in the form of a cookie. 3. For example, http:///mail.html link becomes https:///www.intranet.example.com/mail.html. The cookie set by the requested web server will be converted into a completely unique cookie before being sent to the user's browser to prevent two cookies with the same name from conflicting. For example, a session ID cookie set by intranet.example.com is renamed intranet.example.com_sessionid before being sent to the user's browser. Additionally, Web VPN replaces references to specific HTML DOM objects like document.cookie. These DOM objects are replaced by scripts that return the value of the DOM object, so that they can be accessed within the security context of the requested site domain.

    SOLUTION: Disable content rewriting for untrusted web servers.

    The vulnerability is reported in CallPilot 201i, 202i, 600r, 703t, 1002rp, and 1005r.

    SOLUTION: The vendor recommends to avoid browsing other web sites while logged in to CallPilot Manager or My CallPilot. ----------------------------------------------------------------------

    TITLE: Citrix Access Gateway Web VPN Same Origin Policy Bypass

    SECUNIA ADVISORY ID: SA37696

    VERIFY ADVISORY: http://secunia.com/advisories/37696/

    DESCRIPTION: A vulnerability has been reported in Citrix Access Gateway, which can be exploited by malicious people to bypass certain security restrictions.

    The vulnerability is caused due to the web-based VPN implementation prepending the same domain to all opened websites. This can be exploited to bypass a browser's same origin policy and e.g. access cookies for normally restricted domains by tricking a user into browsing to a malicious website via the VPN.

    The vulnerability is reported in Citrix Access Gateway Enterprise Edition versions 8.1 and later, and all supported Citrix Access Gateway Advanced Edition versions.

    SOLUTION: Do not allow access to untrusted domains via the VPN. Please see the vendor's advisory for more information.

        "data": "Multiple clientless SSL VPN products that run in web browsers, including Stonesoft StoneGate; Cisco ASA; SonicWALL E-Class SSL VPN and SonicWALL SSL VPN; SafeNet SecureWire Access Gateway; Juniper Networks Secure Access; Nortel CallPilot; Citrix Access Gateway; and other products, when running in configurations that do not restrict access to the same domain as the VPN, retrieve the content of remote URLs from one domain and rewrite them so they originate from the VPN\u0027s domain, which violates the same origin policy and allows remote attackers to conduct cross-site scripting attacks, read cookies that originated from other domains, access the Web VPN session to gain access to internal resources, perform key logging, and conduct other attacks.  NOTE: it could be argued that this is a fundamental design problem in any clientless VPN solution, as opposed to a commonly-introduced error that can be fixed in separate implementations. Therefore a single CVE has been assigned for all products that have this design. An attacker could use these devices to bypass authentication or conduct other web-based attacks. plural SSL VPN (Web VPN) There is a problem with the product that can bypass the security mechanism of the web browser. SL VPN (Web VPN) Network resources within an organization using a web browser ( Web server, mail server, etc. ) It is a product to provide a safe access method. SSL VPN (Web VPN) The product rewrites content as necessary as a proxy between the web browser and the server. SSL VPN (Web VPN) Web browser security mechanisms by accessing crafted web pages through (Same Origin Policy) May be bypassed. SSL VPN (Web VPN) Products that implement may be affected by this vulnerability.When a user views a specially crafted page, a remote third party VPN Or hijacking your session SSL VPN (Web VPN) There is a possibility that the content accessed through the site may be viewed or altered. \nAttackers may exploit this issue to violate the same-origin policy to obtain VPN session tokens, read or modify cookie-based authentication credentials, or perform unauthorized actions with the privileges of the web-based VPN domain.  Other attacks may also be possible. \nClientless SSL VPN products from Cisco, Juniper Networks, and SonicWall are vulnerable.  Other vendors\u0027 products may also be affected.  We will update this BID as more information emerges. 2. Web VPN authenticates the user and assigns an ID to the session, which is sent to the user\u0027s browser in the form of a cookie. 3. For example, http://\u003cwww.intranet.example.com\u003e/mail.html link becomes https://\u003cwebvpnserver\u003e/www.intranet.example.com/mail.html. The cookie set by the requested web server will be converted into a completely unique cookie before being sent to the user\u0027s browser to prevent two cookies with the same name from conflicting. For example, a session ID cookie set by intranet.example.com is renamed intranet.example.com_sessionid before being sent to the user\u0027s browser. Additionally, Web VPN replaces references to specific HTML DOM objects like document.cookie. These DOM objects are replaced by scripts that return the value of the DOM object, so that they can be accessed within the security context of the requested site domain. \n\nSOLUTION:\nDisable content rewriting for untrusted web servers.   \n\nThe vulnerability is reported in CallPilot 201i, 202i, 600r, 703t,\n1002rp, and 1005r. \n\nSOLUTION:\nThe vendor recommends to avoid browsing other web sites while logged\nin to CallPilot Manager or My CallPilot. ----------------------------------------------------------------------\n\nDo you have VARM strategy implemented?\n\n(Vulnerability Assessment Remediation Management)  \n\nIf not, then implement it through the most reliable vulnerability\nintelligence source on the market. \n\nImplement it through Secunia. \n\nFor more information visit:\nhttp://secunia.com/advisories/business_solutions/\n\nAlternatively request a call from a Secunia representative today to\ndiscuss how we can help you with our capabilities contact us at:\nsales@secunia.com\n\n----------------------------------------------------------------------\n\nTITLE:\nCitrix Access Gateway Web VPN Same Origin Policy Bypass\n\nSECUNIA ADVISORY ID:\nSA37696\n\nVERIFY ADVISORY:\nhttp://secunia.com/advisories/37696/\n\nDESCRIPTION:\nA vulnerability has been reported in Citrix Access Gateway, which can\nbe exploited by malicious people to bypass certain security\nrestrictions. \n\nThe vulnerability is caused due to the web-based VPN implementation\nprepending the same domain to all opened websites. This can be\nexploited to bypass a browser\u0027s same origin policy and e.g. access\ncookies for normally restricted domains by tricking a user into\nbrowsing to a malicious website via the VPN.   \n\nThe vulnerability is reported in Citrix Access Gateway Enterprise\nEdition versions 8.1 and later, and all supported Citrix Access\nGateway Advanced Edition versions. \n\nSOLUTION:\nDo not allow access to untrusted domains via the VPN. Please see the\nvendor\u0027s advisory for more information. \n\nPROVIDED AND/OR DISCOVERED BY:\nUS-CERT credits Michal Zalewski and Mike Zusman for the original\nreport. \n\nAdditional vulnerability details provided by David Warren and Ryan\nGiobbi of US-CERT. \n\nORIGINAL ADVISORY:\nCitrix:\nhttp://support.citrix.com/article/CTX123610\n\nUS-CERT VU#261869:\nhttp://www.kb.cert.org/vuls/id/261869\n\n----------------------------------------------------------------------\n\nAbout:\nThis Advisory was delivered by Secunia as a free service to help\neverybody keeping their systems up to date against the latest\nvulnerabilities. \n\nSubscribe:\nhttp://secunia.com/advisories/secunia_security_advisories/\n\nDefinitions: (Criticality, Where etc.)\nhttp://secunia.com/advisories/about_secunia_advisories/\n\n\nPlease Note:\nSecunia recommends that you verify all advisories you receive by\nclicking the link. \nSecunia NEVER sends attached files with advisories. \nSecunia does not advise people to install third party patches, only\nuse those supplied by the vendor. \n\n----------------------------------------------------------------------\n\nUnsubscribe: Secunia Security Advisories\nhttp://secunia.com/sec_adv_unsubscribe/?email=packet%40packetstormsecurity.org\n\n----------------------------------------------------------------------\n\n\n",

    Vulnerability from variot - Updated: 2023-12-18 12:10

    The ELF file parser in AhnLab V3 Internet Security 2011.01.18.00, Bitdefender 7.2, Quick Heal (aka Cat QuickHeal) 11.00, Command Antivirus 5.2.11.5, Comodo Antivirus 7424, eSafe 7.0.17.0, F-Prot Antivirus 4.6.2.117, F-Secure Anti-Virus 9.0.16160.0, McAfee Anti-Virus Scanning Engine 5.400.0.1158, Norman Antivirus 6.06.12, nProtect Anti-Virus 2011-01-17.01, and Panda Antivirus 10.0.2.7 allows remote attackers to bypass malware detection via an ELF file with a modified endianness field. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different ELF parser implementations. Multiple products ELF A file parser contains a vulnerability that can prevent malware detection. Different ELF Parser If it is announced that there is also a problem with the implementation of CVE May be split.The endian field changed by a third party ELF Malware detection may be avoided via files. Successful exploits will allow attackers to bypass on-demand virus scanning, possibly allowing malicious files to escape detection

If the length field in the header of a file with test EICAR virus included into a TAR archive is set to be greater than the archive's total length (1,000,000+original length in our experiments), the antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    Affected products - AntiVir 7.11.1.163, Antiy-AVL 2.0.3.7, Avast 4.8.1351.0, Avast5 5.0.677.0, AVG 10.0.0.1190, BitDefender 7.2, CAT-QuickHeal 11.00, ClamAV 0.96.4, Command 5.2.11.5, Emsisoft 5.1.0.1, eSafe 7.0.17.0, F-Prot 4.6.2.117, GData 21, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, Microsoft 1.6402, NOD32 5795, Norman 6.06.12, PCTools 7.0.3.5, Rising 22.83.00.03, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2, VirusBuster 13.6.151.0

    CVE no - CVE-2012-1457

    1. A Windows Compiled HTML Help (CHM) file is a set of HTML files, scripts, and images compressed using the LZX algorithm. For faster random accesses, the algorithm is reset at intervals instead of compressing the entire file as a single stream. The length of each interval is specified in the LZXC header.

    If an infected CHM file's header modified so that the reset interval is lower than in the original file, the antivirus declares the file to be clean. But the Windows CHM viewer hh.exe correctly decompresses the infected content located before the tampered header.

    Affected products - ClamAV 0.96.4, Sophos 4.61.0

    CVE no - CVE-2012-1458

    1. In a POSIX TAR archive, each member file has a 512-byte header protected by a simple checksum. Every header also contains a file length field, which is used by the extractor to locate the next header in the archive.

    If a TAR archive contains two files: the first one is clean, while the second is infected with test EICAR virus - and it is modified such that the length field in the header of the first, clean file to point into the middle of the header of the second, infected file. The antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    CVE no - CVE-2012-1462

    1. In most ELF files, the 5th byte of the header indicates endianness: 01 for little-endian, 02 for bigendian. Linux kernel, however, does not check this field before loading an ELF file. If an infected ELF file's 5-th byte is set to 02, the antivirus declares the file to be clean but the ELF file gets executed correctly.

The\n   length of each interval is specified in the LZXC header. \n\n   If an infected CHM file\u0027s header modified so that the reset interval\n   is lower than in the original file, the antivirus declares the file\n   to be clean. But the Windows CHM viewer hh.exe correctly decompresses\n   the infected content located before the tampered header. \n\n   Affected products -\n   ClamAV 0.96.4, Sophos 4.61.0 \n\n   CVE no - \n   CVE-2012-1458\n\n41. In a POSIX TAR archive, each member file has a 512-byte header protected\n   by a simple checksum. Every header also contains a file length field, which\n   is used by the extractor to locate the next header in the archive. \n\n   If a TAR archive contains two files: the first one is clean, while\n   the second is infected with test EICAR virus - and it is modified such that \n   the length field in the header of the first, clean file to point into the \n   middle of the header of the second, infected file.

    CVE no - CVE-2012-1456

    1. If the length field in the header of a file with test EICAR virus included into a TAR archive is set to be greater than the archive's total length (1,000,000+original length in our experiments), the antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    CVE no - CVE-2012-1457

    1. A Windows Compiled HTML Help (CHM) file is a set of HTML files, scripts, and images compressed using the LZX algorithm. For faster random accesses, the algorithm is reset at intervals instead of compressing the entire file as a single stream. The length of each interval is specified in the LZXC header.

    If an infected CHM file's header modified so that the reset interval is lower than in the original file, the antivirus declares the file to be clean. But the Windows CHM viewer hh.exe correctly decompresses the infected content located before the tampered header.

    Affected products - ClamAV 0.96.4, Sophos 4.61.0

    CVE no - CVE-2012-1458

    1. In a POSIX TAR archive, each member file has a 512-byte header protected by a simple checksum. Every header also contains a file length field, which is used by the extractor to locate the next header in the archive.

    If a TAR archive contains two files: the first one is clean, while the second is infected with test EICAR virus - and it is modified such that the length field in the header of the first, clean file to point into the middle of the header of the second, infected file. The antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program. If an infected tar.gz archive is appended 6 random bytes at the end, the antivirus declares the file to be clean but virus gets extracted by the gunzip+tar programs correctly by ignoring these bytes.

    Affected products - Antiy-AVL 2.0.3.7, CAT-QuickHeal 11.00, Command 5.2.11.5, eSafe 7.0.17.0, F-Prot 4.6.2.117, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, VBA32 3.12.14.2

    CVE no - CVE-2012-1460

    1. GZIP files can contain multiple compressed streams, which are assembled when the contents are extracted. If an infected .tar.gz file is broken into two streams, the antivirus declares the infected .tar.gz file to be clean while tar+gunzip extract the virus correctly

    Affected products - AVG 10.0.0.1190, BitDefender 7.2, Command 5.2.11.5, Emsisoft 5.1.0.1, F-Secure 9.0.16160.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, NOD32 5795, Norman 6.06.12, Rising 22.83.00.03, Sophos 4.61.0, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2

    CVE no - CVE-2012-1461

    1. If an infected ZIP archive is prepended with 1024 random bytes at the beginning, the antivirus declares the file to be clean but virus gets extracted by the unzip program correctly by skipping these bytes

    CVE no - CVE-2012-1462

    1. In most ELF files, the 5th byte of the header indicates endianness: 01 for little-endian, 02 for bigendian. Linux kernel, however, does not check this field before loading an ELF file. If an infected ELF file's 5-th byte is set to 02, the antivirus declares the file to be clean but the ELF file gets executed correctly.

    VAR-201203-0371

    Vulnerability from variot - Updated: 2023-12-18 12:10

    The ELF file parser in Fortinet Antivirus 4.2.254.0, eSafe 7.0.17.0, Dr.Web 5.0.2.03300, and Panda Antivirus 10.0.2.7 allows remote attackers to bypass malware detection via an ELF file with a modified e_version field. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different ELF parser implementations. Successful exploits will allow attackers to bypass on-demand virus scanning, possibly allowing malicious files to escape detection. The following products are affected: DrWeb Antivirus 5.0.2.03300 Panda Antivirus 10.0.2.7. Fortinet Antivirus is an antivirus software designed by Fortinet Company using signature database and heuristic scanning engine

    Vulnerability from variot - Updated: 2023-12-18 12:10

    The ELF file parser in eSafe 7.0.17.0, Prevx 3.0, Fortinet Antivirus 4.2.254.0, and Panda Antivirus 10.0.2.7 allows remote attackers to bypass malware detection via an ELF file with a modified abiversion field. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different ELF parser implementations. Successful exploits will allow attackers to bypass on-demand virus scanning, possibly allowing malicious files to escape detection. The following products are affected: Fortinent Fortinent Antivirus 4.2.254.0 Prevx Prevx 3.0 eSafe Antivirus 7.0.017 0 Panda Antivirus 10.0.2.7. Multiple file-parsing vulnerabilities leading to evasion in different antivirus(AV) products. All affected products are command-line versions of the AVs.

    CVE no - CVE-2012-1456

    1. If the length field in the header of a file with test EICAR virus included into a TAR archive is set to be greater than the archive's total length (1,000,000+original length in our experiments), the antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    Affected products - AntiVir 7.11.1.163, Antiy-AVL 2.0.3.7, Avast 4.8.1351.0, Avast5 5.0.677.0, AVG 10.0.0.1190, BitDefender 7.2, CAT-QuickHeal 11.00, ClamAV 0.96.4, Command 5.2.11.5, Emsisoft 5.1.0.1, eSafe 7.0.17.0, F-Prot 4.6.2.117, GData 21, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, Microsoft 1.6402, NOD32 5795, Norman 6.06.12, PCTools 7.0.3.5, Rising 22.83.00.03, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2, VirusBuster 13.6.151.0

    CVE no - CVE-2012-1457

    1. A Windows Compiled HTML Help (CHM) file is a set of HTML files, scripts, and images compressed using the LZX algorithm. For faster random accesses, the algorithm is reset at intervals instead of compressing the entire file as a single stream. The length of each interval is specified in the LZXC header.

    If an infected CHM file's header modified so that the reset interval is lower than in the original file, the antivirus declares the file to be clean. But the Windows CHM viewer hh.exe correctly decompresses the infected content located before the tampered header.

    Affected products - ClamAV 0.96.4, Sophos 4.61.0

    CVE no - CVE-2012-1458

    1. In a POSIX TAR archive, each member file has a 512-byte header protected by a simple checksum. Every header also contains a file length field, which is used by the extractor to locate the next header in the archive.

    If a TAR archive contains two files: the first one is clean, while the second is infected with test EICAR virus - and it is modified such that the length field in the header of the first, clean file to point into the middle of the header of the second, infected file. The antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    Vulnerability from variot - Updated: 2023-12-18 12:10

    The ELF file parser in eSafe 7.0.17.0, Rising Antivirus 22.83.00.03, Fortinet Antivirus 4.2.254.0, and Panda Antivirus 10.0.2.7 allows remote attackers to bypass malware detection via an ELF file with a modified padding field. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different ELF parser implementations. Successful exploits will allow attackers to bypass on-demand virus scanning, possibly allowing malicious files to escape detection. The following products are affected: eSafe Antivirus 7.0.17.0 Rising Antivirus 22.83.00.03 Panda Antivirus 10.0.2.7. Multiple file-parsing vulnerabilities leading to evasion in different antivirus(AV) products. All affected products are command-line versions of the AVs.

    Affected products - AntiVir 7.11.1.163, Antiy-AVL 2.0.3.7, Avast 4.8.1351.0, Avast5 5.0.677.0, AVG 10.0.0.1190, BitDefender 7.2, CAT-QuickHeal 11.00, ClamAV 0.96.4, Command 5.2.11.5, Emsisoft 5.1.0.1, eSafe 7.0.17.0, F-Prot 4.6.2.117, GData 21, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, Microsoft 1.6402, NOD32 5795, Norman 6.06.12, PCTools 7.0.3.5, Rising 22.83.00.03, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2, VirusBuster 13.6.151.0

    CVE no - CVE-2012-1457

    1. A Windows Compiled HTML Help (CHM) file is a set of HTML files, scripts, and images compressed using the LZX algorithm. For faster random accesses, the algorithm is reset at intervals instead of compressing the entire file as a single stream. The length of each interval is specified in the LZXC header.

    If an infected CHM file's header modified so that the reset interval is lower than in the original file, the antivirus declares the file to be clean. But the Windows CHM viewer hh.exe correctly decompresses the infected content located before the tampered header.

    Affected products - ClamAV 0.96.4, Sophos 4.61.0

    CVE no - CVE-2012-1458

    1. In a POSIX TAR archive, each member file has a 512-byte header protected by a simple checksum. Every header also contains a file length field, which is used by the extractor to locate the next header in the archive.

    If a TAR archive contains two files: the first one is clean, while the second is infected with test EICAR virus - and it is modified such that the length field in the header of the first, clean file to point into the middle of the header of the second, infected file. The antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    CVE no - CVE-2012-1459

    1. If an infected tar.gz archive is appended 6 random bytes at the end, the antivirus declares the file to be clean but virus gets extracted by the gunzip+tar programs correctly by ignoring these bytes.

    Affected products - Antiy-AVL 2.0.3.7, CAT-QuickHeal 11.00, Command 5.2.11.5, eSafe 7.0.17.0, F-Prot 4.6.2.117, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, VBA32 3.12.14.2

    CVE no - CVE-2012-1460

    1. GZIP files can contain multiple compressed streams, which are assembled when the contents are extracted. If an infected .tar.gz file is broken into two streams, the antivirus declares the infected .tar.gz file to be clean while tar+gunzip extract the virus correctly

    Affected products - AVG 10.0.0.1190, BitDefender 7.2, Command 5.2.11.5, Emsisoft 5.1.0.1, F-Secure 9.0.16160.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, NOD32 5795, Norman 6.06.12, Rising 22.83.00.03, Sophos 4.61.0, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2

    CVE no - CVE-2012-1461

    1. If an infected ZIP archive is prepended with 1024 random bytes at the beginning, the antivirus declares the file to be clean but virus gets extracted by the unzip program correctly by skipping these bytes

    Affected products - AhnLab-V3 2011.01.18.00, AVG 10.0.0.1190, CAT-QuickHeal 11.00, Emsisoft 5.1.0.1, eSafe 7.0.17.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, Kaspersky 7.0.0.125, Norman 6.06.12, Sophos 4.61.0, Symantec 20101.3.0.103

    CVE no - CVE-2012-1462

    1. In most ELF files, the 5th byte of the header indicates endianness: 01 for little-endian, 02 for bigendian. Linux kernel, however, does not check this field before loading an ELF file. If an infected ELF file's 5-th byte is set to 02, the antivirus declares the file to be clean but the ELF file gets executed correctly.

    1. A specially crafted ZIP file, created by concatenating the contents of a clean TAR archive and a virus-infected ZIP archive, is parsed incorrectly and evades detection. If the length field in the header of a file with test EICAR virus included into a TAR archive is set to be greater than the archive's total length (1,000,000+original length in our experiments), the antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    Affected products - AntiVir 7.11.1.163, Antiy-AVL 2.0.3.7, Avast 4.8.1351.0, Avast5 5.0.677.0, AVG 10.0.0.1190, BitDefender 7.2, CAT-QuickHeal 11.00, ClamAV 0.96.4, Command 5.2.11.5, Emsisoft 5.1.0.1, eSafe 7.0.17.0, F-Prot 4.6.2.117, GData 21, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, Microsoft 1.6402, NOD32 5795, Norman 6.06.12, PCTools 7.0.3.5, Rising 22.83.00.03, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2, VirusBuster 13.6.151.0

    CVE no - CVE-2012-1457

    1. A Windows Compiled HTML Help (CHM) file is a set of HTML files, scripts, and images compressed using the LZX algorithm. For faster random accesses, the algorithm is reset at intervals instead of compressing the entire file as a single stream. The length of each interval is specified in the LZXC header.

    If an infected CHM file's header modified so that the reset interval is lower than in the original file, the antivirus declares the file to be clean. But the Windows CHM viewer hh.exe correctly decompresses the infected content located before the tampered header.

    Affected products - ClamAV 0.96.4, Sophos 4.61.0

    CVE no - CVE-2012-1458

    1. In a POSIX TAR archive, each member file has a 512-byte header protected by a simple checksum. Every header also contains a file length field, which is used by the extractor to locate the next header in the archive.

    If a TAR archive contains two files: the first one is clean, while the second is infected with test EICAR virus - and it is modified such that the length field in the header of the first, clean file to point into the middle of the header of the second, infected file. The antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    Affected products - AhnLab-V3 2011.01.18.00, AntiVir 7.11.1.163, Antiy-AVL 2.0.3.7, Avast 4.8.1351.0, Avast5 5.0.677.0, AVG 10.0.0.1190, BitDefender 7.2, CAT-QuickHeal 11.00, ClamAV 0.96.4, Command 5.2.11.5, Comodo 7424, Emsisoft 5.1.0.1, F-Prot 4.6.2.117, F-Secure 9.0.16160.0, Fortinent 4.2.254.0, GData 21, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, Microsoft 1.6402, NOD32 5795, Norman 6.06.12, nProtect 2011-01-17.01, Panda 10.0.2.7, PCTools 7.0.3.5, Rising 22.83.00.03, Sophos 4.61.0, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2, VirusBuster 13.6.151.0

    CVE no - CVE-2012-1459

    1. If an infected tar.gz archive is appended 6 random bytes at the end, the antivirus declares the file to be clean but virus gets extracted by the gunzip+tar programs correctly by ignoring these bytes.

    Affected products - Antiy-AVL 2.0.3.7, CAT-QuickHeal 11.00, Command 5.2.11.5, eSafe 7.0.17.0, F-Prot 4.6.2.117, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, VBA32 3.12.14.2

    CVE no - CVE-2012-1460

    1. GZIP files can contain multiple compressed streams, which are assembled when the contents are extracted. If an infected .tar.gz file is broken into two streams, the antivirus declares the infected .tar.gz file to be clean while tar+gunzip extract the virus correctly

    Affected products - AVG 10.0.0.1190, BitDefender 7.2, Command 5.2.11.5, Emsisoft 5.1.0.1, F-Secure 9.0.16160.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, NOD32 5795, Norman 6.06.12, Rising 22.83.00.03, Sophos 4.61.0, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2

    CVE no - CVE-2012-1461

    1. If an infected ZIP archive is prepended with 1024 random bytes at the beginning, the antivirus declares the file to be clean but virus gets extracted by the unzip program correctly by skipping these bytes

    Affected products - AhnLab-V3 2011.01.18.00, AVG 10.0.0.1190, CAT-QuickHeal 11.00, Emsisoft 5.1.0.1, eSafe 7.0.17.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, Kaspersky 7.0.0.125, Norman 6.06.12, Sophos 4.61.0, Symantec 20101.3.0.103

    CVE no - CVE-2012-1462

    1. In most ELF files, the 5th byte of the header indicates endianness: 01 for little-endian, 02 for bigendian. Linux kernel, however, does not check this field before loading an ELF file. If an infected ELF file's 5-th byte is set to 02, the antivirus declares the file to be clean but the ELF file gets executed correctly.

    Affected products - AhnLab-V3 2011.01.18.00, BitDefender 7.2, CAT-QuickHeal 11.00, Command 5.2.11.5, Comodo 7424, eSafe 7.0.17.0, F-Prot 4.6.2.117, F-Secure 9.0.16160.0, McAfee 5.400.0.1158, Norman 6.06.12, nProtect 2011-01-17.01, Panda 10.0.2.7

    1. A specially crafted ZIP file, created by concatenating the contents of a clean TAR archive and a virus-infected ZIP archive, is parsed incorrectly and evades detection. If the length field in the header of a file with test EICAR virus included into a TAR archive is set to be greater than the archive's total length (1,000,000+original length in our experiments), the antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    Affected products - AntiVir 7.11.1.163, Antiy-AVL 2.0.3.7, Avast 4.8.1351.0, Avast5 5.0.677.0, AVG 10.0.0.1190, BitDefender 7.2, CAT-QuickHeal 11.00, ClamAV 0.96.4, Command 5.2.11.5, Emsisoft 5.1.0.1, eSafe 7.0.17.0, F-Prot 4.6.2.117, GData 21, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, Microsoft 1.6402, NOD32 5795, Norman 6.06.12, PCTools 7.0.3.5, Rising 22.83.00.03, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2, VirusBuster 13.6.151.0

    CVE no - CVE-2012-1457

    1. A Windows Compiled HTML Help (CHM) file is a set of HTML files, scripts, and images compressed using the LZX algorithm. For faster random accesses, the algorithm is reset at intervals instead of compressing the entire file as a single stream. The length of each interval is specified in the LZXC header.

    If an infected CHM file's header modified so that the reset interval is lower than in the original file, the antivirus declares the file to be clean. But the Windows CHM viewer hh.exe correctly decompresses the infected content located before the tampered header.

    Affected products - ClamAV 0.96.4, Sophos 4.61.0

    CVE no - CVE-2012-1458

    1. In a POSIX TAR archive, each member file has a 512-byte header protected by a simple checksum. Every header also contains a file length field, which is used by the extractor to locate the next header in the archive.

    If a TAR archive contains two files: the first one is clean, while the second is infected with test EICAR virus - and it is modified such that the length field in the header of the first, clean file to point into the middle of the header of the second, infected file. The antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program. If an infected tar.gz archive is appended 6 random bytes at the end, the antivirus declares the file to be clean but virus gets extracted by the gunzip+tar programs correctly by ignoring these bytes.

    Affected products - Antiy-AVL 2.0.3.7, CAT-QuickHeal 11.00, Command 5.2.11.5, eSafe 7.0.17.0, F-Prot 4.6.2.117, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, VBA32 3.12.14.2

    CVE no - CVE-2012-1460

    1. GZIP files can contain multiple compressed streams, which are assembled when the contents are extracted. If an infected ZIP archive is prepended with 1024 random bytes at the beginning, the antivirus declares the file to be clean but virus gets extracted by the unzip program correctly by skipping these bytes

    Affected products - AhnLab-V3 2011.01.18.00, AVG 10.0.0.1190, CAT-QuickHeal 11.00, Emsisoft 5.1.0.1, eSafe 7.0.17.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, Kaspersky 7.0.0.125, Norman 6.06.12, Sophos 4.61.0, Symantec 20101.3.0.103

    CVE no - CVE-2012-1462

    1. In most ELF files, the 5th byte of the header indicates endianness: 01 for little-endian, 02 for bigendian. Linux kernel, however, does not check this field before loading an ELF file. If an infected ELF file's 5-th byte is set to 02, the antivirus declares the file to be clean but the ELF file gets executed correctly.

A Windows Compiled HTML Help (CHM) file is a set of HTML files,\n   scripts, and images compressed using the LZX algorithm. \n   For faster random accesses, the algorithm is reset at intervals\n   instead of compressing the entire file as a single stream. The\n   length of each interval is specified in the LZXC header. \n\n   If an infected CHM file\u0027s header modified so that the reset interval\n   is lower than in the original file, the antivirus declares the file\n   to be clean. But the Windows CHM viewer hh.exe correctly decompresses\n   the infected content located before the tampered header. \n\n   Affected products -\n   ClamAV 0.96.4, Sophos 4.61.0 \n\n   CVE no - \n   CVE-2012-1458\n\n41. In a POSIX TAR archive, each member file has a 512-byte header protected\n   by a simple checksum. Every header also contains a file length field, which\n   is used by the extractor to locate the next header in the archive. \n\n   If a TAR archive contains two files: the first one is clean, while\n   the second is infected with test EICAR virus - and it is modified such that \n   the length field in the header of the first, clean file to point into the \n   middle of the header of the second, infected file. The antivirus declares \n   the file to be clean but virus gets extracted correctly by the \n   GNU tar program. If an infected tar.gz archive is appended 6 random bytes at the end, \n    the antivirus declares the file to be clean but virus gets extracted by\n    the gunzip+tar programs correctly by ignoring these bytes. \n\n   Affected products -\n   Antiy-AVL 2.0.3.7, CAT-QuickHeal 11.00, Command 5.2.11.5, \n   eSafe 7.0.17.0, F-Prot 4.6.2.117, Jiangmin 13.0.900, \n   K7AntiVirus 9.77.3565, VBA32 3.12.14.2 \n   \n   CVE no - \n   CVE-2012-1460\n\n43. GZIP files can contain multiple compressed streams, which are assembled\n    when the contents are extracted. If an infected ZIP archive is prepended with 1024 random bytes at the \n   beginning, the antivirus declares the file to be clean but virus gets extracted\n   by the unzip program correctly by skipping these bytes\n\n   Affected products -\n   AhnLab-V3 2011.01.18.00, AVG 10.0.0.1190, CAT-QuickHeal 11.00, \n   Emsisoft 5.1.0.1, eSafe 7.0.17.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, \n   Jiangmin 13.0.900, Kaspersky 7.0.0.125, Norman 6.06.12, Sophos 4.61.0, \n   Symantec 20101.3.0.103 \n\n   CVE no - \n   CVE-2012-1462\n\n45. In most ELF files, the 5th byte of the header indicates endianness: 01\n   for little-endian, 02 for bigendian. Linux kernel, however, does not\n   check this field before loading an ELF file.

    Vulnerability from variot - Updated: 2023-12-18 12:10

    The ELF file parser in Dr.Web 5.0.2.03300, eSafe 7.0.17.0, McAfee Gateway (formerly Webwasher) 2010.1C, Rising Antivirus 22.83.00.03, Fortinet Antivirus 4.2.254.0, and Panda Antivirus 10.0.2.7 allows remote attackers to bypass malware detection via an ELF file with a modified ei_version field. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different ELF parser implementations. Multiple products ELF There are vulnerabilities in parsers that prevent malware detection. Multiple Antivirus products are prone to a vulnerability that may allow an attacker to bypass on-demand scans. Successful exploits will allow attackers to bypass on-demand virus scanning, possibly allowing malicious files to escape detection. The following products are affected: eSafe Antivirus 7.0.17.0 McAfee McAfee-GW-Edition 2010.1C Rising Antivirus 22.83.00.03 Panda Antivirus 10.0.2.7

If the length field in the header of a file with test EICAR virus included into a TAR archive is set to be greater than the archive's total length (1,000,000+original length in our experiments), the antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    Affected products - AntiVir 7.11.1.163, Antiy-AVL 2.0.3.7, Avast 4.8.1351.0, Avast5 5.0.677.0, AVG 10.0.0.1190, BitDefender 7.2, CAT-QuickHeal 11.00, ClamAV 0.96.4, Command 5.2.11.5, Emsisoft 5.1.0.1, eSafe 7.0.17.0, F-Prot 4.6.2.117, GData 21, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, Microsoft 1.6402, NOD32 5795, Norman 6.06.12, PCTools 7.0.3.5, Rising 22.83.00.03, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2, VirusBuster 13.6.151.0

    CVE no - CVE-2012-1457

    1. A Windows Compiled HTML Help (CHM) file is a set of HTML files, scripts, and images compressed using the LZX algorithm. For faster random accesses, the algorithm is reset at intervals instead of compressing the entire file as a single stream. The length of each interval is specified in the LZXC header.

    If an infected CHM file's header modified so that the reset interval is lower than in the original file, the antivirus declares the file to be clean. But the Windows CHM viewer hh.exe correctly decompresses the infected content located before the tampered header.

    Affected products - ClamAV 0.96.4, Sophos 4.61.0

    CVE no - CVE-2012-1458

    1. In a POSIX TAR archive, each member file has a 512-byte header protected by a simple checksum. Every header also contains a file length field, which is used by the extractor to locate the next header in the archive.

    If a TAR archive contains two files: the first one is clean, while the second is infected with test EICAR virus - and it is modified such that the length field in the header of the first, clean file to point into the middle of the header of the second, infected file. The antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program. If an infected tar.gz archive is appended 6 random bytes at the end, the antivirus declares the file to be clean but virus gets extracted by the gunzip+tar programs correctly by ignoring these bytes.

    Affected products - Antiy-AVL 2.0.3.7, CAT-QuickHeal 11.00, Command 5.2.11.5, eSafe 7.0.17.0, F-Prot 4.6.2.117, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, VBA32 3.12.14.2

    CVE no - CVE-2012-1460

    1. GZIP files can contain multiple compressed streams, which are assembled when the contents are extracted. If an infected .tar.gz file is broken into two streams, the antivirus declares the infected .tar.gz file to be clean while tar+gunzip extract the virus correctly

    Affected products - AVG 10.0.0.1190, BitDefender 7.2, Command 5.2.11.5, Emsisoft 5.1.0.1, F-Secure 9.0.16160.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, NOD32 5795, Norman 6.06.12, Rising 22.83.00.03, Sophos 4.61.0, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2

    CVE no - CVE-2012-1461

    1. If an infected ZIP archive is prepended with 1024 random bytes at the beginning, the antivirus declares the file to be clean but virus gets extracted by the unzip program correctly by skipping these bytes

    Affected products - AhnLab-V3 2011.01.18.00, AVG 10.0.0.1190, CAT-QuickHeal 11.00, Emsisoft 5.1.0.1, eSafe 7.0.17.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, Kaspersky 7.0.0.125, Norman 6.06.12, Sophos 4.61.0, Symantec 20101.3.0.103

    CVE no - CVE-2012-1462

    1. In most ELF files, the 5th byte of the header indicates endianness: 01 for little-endian, 02 for bigendian. Linux kernel, however, does not check this field before loading an ELF file. If an infected ELF file's 5-th byte is set to 02, the antivirus declares the file to be clean but the ELF file gets executed correctly.

A Windows Compiled HTML Help (CHM) file is a set of HTML files,\n   scripts, and images compressed using the LZX algorithm. \n   For faster random accesses, the algorithm is reset at intervals\n   instead of compressing the entire file as a single stream. The\n   length of each interval is specified in the LZXC header. \n\n   If an infected CHM file\u0027s header modified so that the reset interval\n   is lower than in the original file, the antivirus declares the file\n   to be clean. But the Windows CHM viewer hh.exe correctly decompresses\n   the infected content located before the tampered header. \n\n   Affected products -\n   ClamAV 0.96.4, Sophos 4.61.0 \n\n   CVE no - \n   CVE-2012-1458\n\n41. In a POSIX TAR archive, each member file has a 512-byte header protected\n   by a simple checksum. Every header also contains a file length field, which\n   is used by the extractor to locate the next header in the archive. \n\n   If a TAR archive contains two files: the first one is clean, while\n   the second is infected with test EICAR virus - and it is modified such that \n   the length field in the header of the first, clean file to point into the \n   middle of the header of the second, infected file. The antivirus declares \n   the file to be clean but virus gets extracted correctly by the \n   GNU tar program. If an infected tar.gz archive is appended 6 random bytes at the end, \n    the antivirus declares the file to be clean but virus gets extracted by\n    the gunzip+tar programs correctly by ignoring these bytes. \n\n   Affected products -\n   Antiy-AVL 2.0.3.7, CAT-QuickHeal 11.00, Command 5.2.11.5, \n   eSafe 7.0.17.0, F-Prot 4.6.2.117, Jiangmin 13.0.900, \n   K7AntiVirus 9.77.3565, VBA32 3.12.14.2 \n   \n   CVE no - \n   CVE-2012-1460\n\n43.

    Vulnerability from variot - Updated: 2023-12-18 12:10

    The ELF file parser in eSafe 7.0.17.0, Rising Antivirus 22.83.00.03, Fortinet Antivirus 4.2.254.0, and Panda Antivirus 10.0.2.7 allows remote attackers to bypass malware detection via an ELF file with a modified abi field. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different ELF parser implementations. Successful exploits will allow attackers to bypass on-demand virus scanning, possibly allowing malicious files to escape detection. The following products are affected: Fortinent Fortinent Antivirus 4.2.254.0 Rising Antivirus 22.83.00.03 eSafe Antivirus 7.0.017 0 Panda Antivirus 10.0.2.7. Multiple file-parsing vulnerabilities leading to evasion in different antivirus(AV) products. All affected products are command-line versions of the AVs.

    1. A specially crafted ZIP file, created by concatenating the contents of a clean TAR archive and a virus-infected ZIP archive, is parsed incorrectly and evades detection. If the length field in the header of a file with test EICAR virus included into a TAR archive is set to be greater than the archive's total length (1,000,000+original length in our experiments), the antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    Affected products - AntiVir 7.11.1.163, Antiy-AVL 2.0.3.7, Avast 4.8.1351.0, Avast5 5.0.677.0, AVG 10.0.0.1190, BitDefender 7.2, CAT-QuickHeal 11.00, ClamAV 0.96.4, Command 5.2.11.5, Emsisoft 5.1.0.1, eSafe 7.0.17.0, F-Prot 4.6.2.117, GData 21, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, Microsoft 1.6402, NOD32 5795, Norman 6.06.12, PCTools 7.0.3.5, Rising 22.83.00.03, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2, VirusBuster 13.6.151.0

    CVE no - CVE-2012-1457

    1. A Windows Compiled HTML Help (CHM) file is a set of HTML files, scripts, and images compressed using the LZX algorithm. For faster random accesses, the algorithm is reset at intervals instead of compressing the entire file as a single stream. The length of each interval is specified in the LZXC header.

    If an infected CHM file's header modified so that the reset interval is lower than in the original file, the antivirus declares the file to be clean. But the Windows CHM viewer hh.exe correctly decompresses the infected content located before the tampered header.

    Affected products - ClamAV 0.96.4, Sophos 4.61.0

    CVE no - CVE-2012-1458

    1. In a POSIX TAR archive, each member file has a 512-byte header protected by a simple checksum. Every header also contains a file length field, which is used by the extractor to locate the next header in the archive.

    If a TAR archive contains two files: the first one is clean, while the second is infected with test EICAR virus - and it is modified such that the length field in the header of the first, clean file to point into the middle of the header of the second, infected file. The antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    CVE no - CVE-2012-1459

    1. If an infected tar.gz archive is appended 6 random bytes at the end, the antivirus declares the file to be clean but virus gets extracted by the gunzip+tar programs correctly by ignoring these bytes.

    Affected products - Antiy-AVL 2.0.3.7, CAT-QuickHeal 11.00, Command 5.2.11.5, eSafe 7.0.17.0, F-Prot 4.6.2.117, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, VBA32 3.12.14.2

    CVE no - CVE-2012-1460

    1. GZIP files can contain multiple compressed streams, which are assembled when the contents are extracted. If an infected .tar.gz file is broken into two streams, the antivirus declares the infected .tar.gz file to be clean while tar+gunzip extract the virus correctly

    Affected products - AVG 10.0.0.1190, BitDefender 7.2, Command 5.2.11.5, Emsisoft 5.1.0.1, F-Secure 9.0.16160.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, NOD32 5795, Norman 6.06.12, Rising 22.83.00.03, Sophos 4.61.0, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2

    CVE no - CVE-2012-1461

    1. If an infected ZIP archive is prepended with 1024 random bytes at the beginning, the antivirus declares the file to be clean but virus gets extracted by the unzip program correctly by skipping these bytes

    Affected products - AhnLab-V3 2011.01.18.00, AVG 10.0.0.1190, CAT-QuickHeal 11.00, Emsisoft 5.1.0.1, eSafe 7.0.17.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, Kaspersky 7.0.0.125, Norman 6.06.12, Sophos 4.61.0, Symantec 20101.3.0.103

    CVE no - CVE-2012-1462

    1. In most ELF files, the 5th byte of the header indicates endianness: 01 for little-endian, 02 for bigendian. Linux kernel, however, does not check this field before loading an ELF file. If an infected ELF file's 5-th byte is set to 02, the antivirus declares the file to be clean but the ELF file gets executed correctly.

    Affected products - AhnLab-V3 2011.01.18.00, BitDefender 7.2, CAT-QuickHeal 11.00, Command 5.2.11.5, Comodo 7424, eSafe 7.0.17.0, F-Prot 4.6.2.117, F-Secure 9.0.16160.0, McAfee 5.400.0.1158, Norman 6.06.12, nProtect 2011-01-17.01, Panda 10.0.2.7

NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different ZIP parser implementations. Multiple products ZIP A file parser contains a vulnerability that can prevent malware detection. Different ZIP Parser If it is announced that there is also a problem with the implementation of CVE May be split.A third party includes an invalid block of data at the beginning ZIP Malware detection may be avoided via files. Successful exploits will allow attackers to bypass on-demand virus scanning, possibly allowing malicious files to escape detection

    CVE no - CVE-2012-1455

    1. A specially crafted ZIP file, created by concatenating the contents of a clean TAR archive and a virus-infected ZIP archive, is parsed incorrectly and evades detection. If the length field in the header of a file with test EICAR virus included into a TAR archive is set to be greater than the archive's total length (1,000,000+original length in our experiments), the antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    Affected products - AntiVir 7.11.1.163, Antiy-AVL 2.0.3.7, Avast 4.8.1351.0, Avast5 5.0.677.0, AVG 10.0.0.1190, BitDefender 7.2, CAT-QuickHeal 11.00, ClamAV 0.96.4, Command 5.2.11.5, Emsisoft 5.1.0.1, eSafe 7.0.17.0, F-Prot 4.6.2.117, GData 21, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, Microsoft 1.6402, NOD32 5795, Norman 6.06.12, PCTools 7.0.3.5, Rising 22.83.00.03, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2, VirusBuster 13.6.151.0

    CVE no - CVE-2012-1457

    1. A Windows Compiled HTML Help (CHM) file is a set of HTML files, scripts, and images compressed using the LZX algorithm. For faster random accesses, the algorithm is reset at intervals instead of compressing the entire file as a single stream. The length of each interval is specified in the LZXC header.

    If an infected CHM file's header modified so that the reset interval is lower than in the original file, the antivirus declares the file to be clean. But the Windows CHM viewer hh.exe correctly decompresses the infected content located before the tampered header.

    Affected products - ClamAV 0.96.4, Sophos 4.61.0

    CVE no - CVE-2012-1458

    1. In a POSIX TAR archive, each member file has a 512-byte header protected by a simple checksum. Every header also contains a file length field, which is used by the extractor to locate the next header in the archive.

    If a TAR archive contains two files: the first one is clean, while the second is infected with test EICAR virus - and it is modified such that the length field in the header of the first, clean file to point into the middle of the header of the second, infected file. The antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program. If an infected tar.gz archive is appended 6 random bytes at the end, the antivirus declares the file to be clean but virus gets extracted by the gunzip+tar programs correctly by ignoring these bytes.

    Affected products - Antiy-AVL 2.0.3.7, CAT-QuickHeal 11.00, Command 5.2.11.5, eSafe 7.0.17.0, F-Prot 4.6.2.117, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, VBA32 3.12.14.2

    CVE no - CVE-2012-1460

    1. GZIP files can contain multiple compressed streams, which are assembled when the contents are extracted. If an infected .tar.gz file is broken into two streams, the antivirus declares the infected .tar.gz file to be clean while tar+gunzip extract the virus correctly

    Affected products - AVG 10.0.0.1190, BitDefender 7.2, Command 5.2.11.5, Emsisoft 5.1.0.1, F-Secure 9.0.16160.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, NOD32 5795, Norman 6.06.12, Rising 22.83.00.03, Sophos 4.61.0, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2

    CVE no - CVE-2012-1461

    1. If an infected ZIP archive is prepended with 1024 random bytes at the beginning, the antivirus declares the file to be clean but virus gets extracted by the unzip program correctly by skipping these bytes

    Affected products - AhnLab-V3 2011.01.18.00, AVG 10.0.0.1190, CAT-QuickHeal 11.00, Emsisoft 5.1.0.1, eSafe 7.0.17.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, Kaspersky 7.0.0.125, Norman 6.06.12, Sophos 4.61.0, Symantec 20101.3.0.103

    CVE no - CVE-2012-1462

    1. In most ELF files, the 5th byte of the header indicates endianness: 01 for little-endian, 02 for bigendian. Linux kernel, however, does not check this field before loading an ELF file. If an infected ELF file's 5-th byte is set to 02, the antivirus declares the file to be clean but the ELF file gets executed correctly.

    Affected products - AhnLab-V3 2011.01.18.00, BitDefender 7.2, CAT-QuickHeal 11.00, Command 5.2.11.5, Comodo 7424, eSafe 7.0.17.0, F-Prot 4.6.2.117, F-Secure 9.0.16160.0, McAfee 5.400.0.1158, Norman 6.06.12, nProtect 2011-01-17.01, Panda 10.0.2.7

If the length field in the header of a file with test EICAR virus included into a TAR archive is set to be greater than the archive's total length (1,000,000+original length in our experiments), the antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program.

    Affected products - AntiVir 7.11.1.163, Antiy-AVL 2.0.3.7, Avast 4.8.1351.0, Avast5 5.0.677.0, AVG 10.0.0.1190, BitDefender 7.2, CAT-QuickHeal 11.00, ClamAV 0.96.4, Command 5.2.11.5, Emsisoft 5.1.0.1, eSafe 7.0.17.0, F-Prot 4.6.2.117, GData 21, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, Microsoft 1.6402, NOD32 5795, Norman 6.06.12, PCTools 7.0.3.5, Rising 22.83.00.03, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2, VirusBuster 13.6.151.0

    CVE no - CVE-2012-1457

    1. A Windows Compiled HTML Help (CHM) file is a set of HTML files, scripts, and images compressed using the LZX algorithm. For faster random accesses, the algorithm is reset at intervals instead of compressing the entire file as a single stream. The length of each interval is specified in the LZXC header.

    If an infected CHM file's header modified so that the reset interval is lower than in the original file, the antivirus declares the file to be clean. But the Windows CHM viewer hh.exe correctly decompresses the infected content located before the tampered header.

    Affected products - ClamAV 0.96.4, Sophos 4.61.0

    CVE no - CVE-2012-1458

    1. In a POSIX TAR archive, each member file has a 512-byte header protected by a simple checksum. Every header also contains a file length field, which is used by the extractor to locate the next header in the archive.

    If a TAR archive contains two files: the first one is clean, while the second is infected with test EICAR virus - and it is modified such that the length field in the header of the first, clean file to point into the middle of the header of the second, infected file. The antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program. If an infected tar.gz archive is appended 6 random bytes at the end, the antivirus declares the file to be clean but virus gets extracted by the gunzip+tar programs correctly by ignoring these bytes.

    Affected products - Antiy-AVL 2.0.3.7, CAT-QuickHeal 11.00, Command 5.2.11.5, eSafe 7.0.17.0, F-Prot 4.6.2.117, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, VBA32 3.12.14.2

    CVE no - CVE-2012-1460

    1. GZIP files can contain multiple compressed streams, which are assembled when the contents are extracted. If an infected .tar.gz file is broken into two streams, the antivirus declares the infected .tar.gz file to be clean while tar+gunzip extract the virus correctly

    Affected products - AVG 10.0.0.1190, BitDefender 7.2, Command 5.2.11.5, Emsisoft 5.1.0.1, F-Secure 9.0.16160.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, NOD32 5795, Norman 6.06.12, Rising 22.83.00.03, Sophos 4.61.0, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2

    CVE no - CVE-2012-1461

    1. If an infected ZIP archive is prepended with 1024 random bytes at the beginning, the antivirus declares the file to be clean but virus gets extracted by the unzip program correctly by skipping these bytes

    Affected products - AhnLab-V3 2011.01.18.00, AVG 10.0.0.1190, CAT-QuickHeal 11.00, Emsisoft 5.1.0.1, eSafe 7.0.17.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, Kaspersky 7.0.0.125, Norman 6.06.12, Sophos 4.61.0, Symantec 20101.3.0.103

    CVE no - CVE-2012-1462

    1. In most ELF files, the 5th byte of the header indicates endianness: 01 for little-endian, 02 for bigendian. Linux kernel, however, does not check this field before loading an ELF file. If an infected ELF file's 5-th byte is set to 02, the antivirus declares the file to be clean but the ELF file gets executed correctly.

    Affected products - AhnLab-V3 2011.01.18.00, BitDefender 7.2, CAT-QuickHeal 11.00, Command 5.2.11.5, Comodo 7424, eSafe 7.0.17.0, F-Prot 4.6.2.117, F-Secure 9.0.16160.0, McAfee 5.400.0.1158, Norman 6.06.12, nProtect 2011-01-17.01, Panda 10.0.2.7

    CVE no - CVE-2012-1463

A Windows Compiled HTML Help (CHM) file is a set of HTML files,\n   scripts, and images compressed using the LZX algorithm. \n   For faster random accesses, the algorithm is reset at intervals\n   instead of compressing the entire file as a single stream. The\n   length of each interval is specified in the LZXC header. \n\n   If an infected CHM file\u0027s header modified so that the reset interval\n   is lower than in the original file, the antivirus declares the file\n   to be clean. But the Windows CHM viewer hh.exe correctly decompresses\n   the infected content located before the tampered header. \n\n   Affected products -\n   ClamAV 0.96.4, Sophos 4.61.0 \n\n   CVE no - \n   CVE-2012-1458\n\n41. In a POSIX TAR archive, each member file has a 512-byte header protected\n   by a simple checksum. Every header also contains a file length field, which\n   is used by the extractor to locate the next header in the archive. \n\n   If a TAR archive contains two files: the first one is clean, while\n   the second is infected with test EICAR virus - and it is modified such that \n   the length field in the header of the first, clean file to point into the \n   middle of the header of the second, infected file. The antivirus declares \n   the file to be clean but virus gets extracted correctly by the \n   GNU tar program. If an infected tar.gz archive is appended 6 random bytes at the end, \n    the antivirus declares the file to be clean but virus gets extracted by\n    the gunzip+tar programs correctly by ignoring these bytes. \n\n   Affected products -\n   Antiy-AVL 2.0.3.7, CAT-QuickHeal 11.00, Command 5.2.11.5, \n   eSafe 7.0.17.0, F-Prot 4.6.2.117, Jiangmin 13.0.900, \n   K7AntiVirus 9.77.3565, VBA32 3.12.14.2 \n   \n   CVE no - \n   CVE-2012-1460\n\n43.

    Vulnerability from variot - Updated: 2023-12-18 11:03

    Off-by-one error in the Ins_MINDEX function in the TrueType bytecode interpreter in Ghostscript before 8.71 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a malformed TrueType font in a document that trigger an integer overflow and a heap-based buffer overflow. Ghostscript of TrueType bytecode interpreter Vulnerabilities exist. Ghostscript is a program for displaying PostScript files or printing files to non-PostScript printers. An attacker can exploit this issue to execute arbitrary code. Failed exploit attempts will likely cause denial-of-service conditions. Versions prior to Ghostscript 8.71 are vulnerable. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201412-17

    ===================================================================== Red Hat Security Advisory

    Synopsis: Moderate: ghostscript security update Advisory ID: RHSA-2012:0095-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0095.html Issue date: 2012-02-02 CVE Names: CVE-2009-3743 CVE-2010-2055 CVE-2010-4054 CVE-2010-4820 =====================================================================

    1. Summary:

    Updated ghostscript packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6.

    The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

    1. Relevant releases/architectures:

    RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64

    1. Description:

    Ghostscript is a set of software that provides a PostScript interpreter, a set of C procedures (the Ghostscript library, which implements the graphics capabilities in the PostScript language) and an interpreter for Portable Document Format (PDF) files. An attacker could create a specially-crafted PostScript or PDF file that, when interpreted, could cause Ghostscript to crash or, potentially, execute arbitrary code. (CVE-2009-3743)

    It was found that Ghostscript always tried to read Ghostscript system initialization files from the current working directory before checking other directories, even if a search path that did not contain the current working directory was specified with the "-I" option, or the "-P-" option was used (to prevent the current working directory being searched first). (CVE-2010-2055)

    Ghostscript included the current working directory in its library search path by default. If a user ran Ghostscript without the "-P-" option in an attacker-controlled directory containing a specially-crafted PostScript library file, it could cause Ghostscript to execute arbitrary PostScript code. With this update, Ghostscript no longer searches the current working directory for library files by default. (CVE-2010-4820)

    Note: The fix for CVE-2010-4820 could possibly break existing configurations. To use the previous, vulnerable behavior, run Ghostscript with the "-P" option (to always search the current working directory first). An attacker could create a specially-crafted PostScript Type 1 or PostScript Type 2 font file that, when interpreted, could cause Ghostscript to crash or, potentially, execute arbitrary code. (CVE-2010-4054)

    Users of Ghostscript are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

    1. Solution:

    Before applying this update, make sure all previously-released errata relevant to your system have been applied.

    This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259

    In general, a standard system update will make all the necessary changes.

    --[ Vulnerability details:

    memove() is defined in string.h and has the following prototype:

    void *memmove(void *dest, const void *src, size_t n);
    

    It is worth noticing that size_t is a signed integer.

    In ghostscript-8.70.dfsg.1/base/ttinterp.c we can find the following code snippet:

    /******/ / MINDEX[] : move indexed element / / CodeRange : $26 */

    static void Ins_MINDEX( INS_ARG ) { Long L, K; [0]

    L = args[0];                [1]
    
    if ( L<0 || L > CUR.args )            [2]
    {
      CUR.error = TT_Err_Invalid_Reference;
      return;
    }
    
    K = CUR.stack[CUR.args - L];        [3]
    
    memmove( (&CUR.stack[CUR.args - L    ]),    [4]
              (&CUR.stack[CUR.args - L + 1]),
              (L - 1) * sizeof ( Long ) );
    
    CUR.stack[ CUR.args-1 ] = K;
    

    }

    [0] L is actually an unsigned long on x86. [1] L is user controled. [2] what if L is null then ? [3] will work fine with L null... [4] if L was null, then the sized passed to memmove is casted from an unsigned long to a signed integer (size_t) worthing 111111111111111111111111111111 in binary, or 0x3fffffff.

    Let's now consider the third argument passed to memmove in [4]. This value is used as a counter in register ecx, resulting in the copy of a very large chunk of memory (0x3fffffff ~= 1Gb). At this time, the destination being somewhere in the heap, the appliation will eventually fill the heap segment with (unexpected) data, and the copy will fail when trying to write to the first non mapped address after the heap in the address space, generating a segmentation fault.

    Experimentally, reaching this codepath has shown to be possible. The values of the registers (in particular ecx and edi) at crash time are coherent with our expectations and the explaination above :

    Program received signal SIGSEGV, Segmentation fault. -------------------------------------------------------------------------[ regs eax:FFFFFFFC ebx:405B6FF4 ecx:3FF85061 edx:0807C844 eflags:00010216 esi:0826A000 edi:08269FFC esp:BFFFDD18 ebp:BFFFDD58 eip:408EFA83 cs:0073 ds:007B es:007B fs:0000 gs:0033 ss:007B o d I t s z A P c [007B:BFFFDD18]---------------------------------------------------------[stack] BFFFDD48 : E0 13 F9 FF F4 6F 5B 40 - 44 C8 07 08 00 00 00 00 .....o[@D.......

    Arbitrary code execution would require to corrupt the heap with a bit more than 1Gb of copied data without writting to invalid memory. Having the heap allocate so much data is not belived to be possible in the current situation under x86 GNU/linux.

    Third party applications linking to this library may also be vulnerable.
    

    --[ Patch:

    This off by one can be mitigated by applying the following patch in
    ghostscript-8.70.dfsg.1/base/ttinterp.c :
    
    • if ( L<0 || L > CUR.args )
    • if ( L<=0 || L > CUR.args )

      The patch that has actually been merged to Ghostscript is strictly equivalent.

    --[ Disclosure timeline:

    • 06/01/2010: Provide full analysis and patches to the vendor.
    • 06/01/2010: Vendor claims to have silently patched the vulnerability in their development branch.
    • 01/03/2010: Ping vendor, who remains silent...
    • 22/03/2010: Ping vendor, who remains silent...
    • 20/07/2010: Inform the CERT about the vulnearbility.
    • 20/07/2010: Recontact CERT about this vulnerability.
    • 03/08/2010: CERT gets back to us asking for details.
    • 09/08/2010: Send available information to the CERT.
    • 13/08/2010: The CERT compares our patch and the applied patch in addition to the material we provided and concludes the vendor actually did fix the vulnerability as we suggested, but silently, denying us any kind of credit.
    • 14/08/2010: The CERT assigns CVE number CVE-2009-3743 to this vulnerability.
    • 25/11/2010: Public disclosure.

    Note: The vendor claims to follow a bounty program for coders fixing bugs in their software. From our experience, they do not practice such a thing but silently patch reported bugs instead. We hope this was merely an exception.

Summary:\n\nUpdated ghostscript packages that fix multiple security issues are now\navailable for Red Hat Enterprise Linux 5 and 6. \n\nThe Red Hat Security Response Team has rated this update as having moderate\nsecurity impact. Common Vulnerability Scoring System (CVSS) base scores,\nwhich give detailed severity ratings, are available for each vulnerability\nfrom the CVE links in the References section. \n\n2.

Description:\n\nGhostscript is a set of software that provides a PostScript interpreter, a\nset of C procedures (the Ghostscript library, which implements the graphics\ncapabilities in the PostScript language) and an interpreter for Portable\nDocument Format (PDF) files. An attacker could create a specially-crafted PostScript or PDF\nfile that, when interpreted, could cause Ghostscript to crash or,\npotentially, execute arbitrary code. (CVE-2009-3743)\n\nIt was found that Ghostscript always tried to read Ghostscript system\ninitialization files from the current working directory before checking\nother directories, even if a search path that did not contain the current\nworking directory was specified with the \"-I\" option, or the \"-P-\" option\nwas used (to prevent the current working directory being searched first). (CVE-2010-2055)\n\nGhostscript included the current working directory in its library search\npath by default. If a user ran Ghostscript without the \"-P-\" option in an\nattacker-controlled directory containing a specially-crafted PostScript\nlibrary file, it could cause Ghostscript to execute arbitrary PostScript\ncode. With this update, Ghostscript no longer searches the current working\ndirectory for library files by default. (CVE-2010-4820)\n\nNote: The fix for CVE-2010-4820 could possibly break existing\nconfigurations. To use the previous, vulnerable behavior, run Ghostscript\nwith the \"-P\" option (to always search the current working directory\nfirst). An attacker could create a specially-crafted\nPostScript Type 1 or PostScript Type 2 font file that, when interpreted,\ncould cause Ghostscript to crash or, potentially, execute arbitrary code. \n(CVE-2010-4054)\n\nUsers of Ghostscript are advised to upgrade to these updated packages,\nwhich contain backported patches to correct these issues. \n\n4. Solution:\n\nBefore applying this update, make sure all previously-released errata\nrelevant to your system have been applied. \n\nThis update is available via the Red Hat Network. Details on how to\nuse the Red Hat Network to apply this update are available at\nhttps://access.redhat.com/kb/docs/DOC-11259\n\n5.

(CVE-2008-3520)\n\nIt was discovered that Ghostscript did not correctly handle certain\nformatting operations when parsing JPEG-2000 images. (CVE-2008-3522)\n\nIt was discovered that Ghostscript incorrectly handled certain malformed\nTrueType fonts. \nThis issue only affected Ubuntu 8.04 LTS. (CVE-2009-3743)\n\nIt was discovered that Ghostscript incorrectly handled certain malformed\nType 2 fonts. \nThis issue only affected Ubuntu 8.04 LTS. (CVE-2010-4054)\n\nJonathan Foote discovered that Ghostscript incorrectly handled certain\nmalformed JPEG-2000 image files. (CVE-2011-4516, CVE-2011-4517)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 10.10:\n  libgs8                          8.71.dfsg.2-0ubuntu7.1\n\nUbuntu 10.04 LTS:\n  libgs8                          8.71.dfsg.1-0ubuntu5.4\n\nUbuntu 8.04 LTS:\n  libgs8                          8.61.dfsg.1-1ubuntu3.4\n\nIn general, a standard system update will make all the necessary changes. \n\n--[ Vulnerability details:\n\nmemove() is defined in string.h and has the following prototype:\n\n    void *memmove(void *dest, const void *src, size_t n);\n\nIt is worth noticing that size_t is a signed integer. \n\nIn ghostscript-8.70.dfsg.1/base/ttinterp.c we can find the following code\nsnippet:\n\n/*******************************************/\n/* MINDEX[]  : move indexed element        */\n/* CodeRange : $26                         */\n\n  static void  Ins_MINDEX( INS_ARG )\n  {\n    Long  L, K;                    [0]\n\n\n    L = args[0];                [1]\n\n    if ( L\u003c0 || L \u003e CUR.args )            [2]\n    {\n      CUR.error = TT_Err_Invalid_Reference;\n      return;\n    }\n\n    K = CUR.stack[CUR.args - L];        [3]\n\n    memmove( (\u0026CUR.stack[CUR.args - L    ]),    [4]\n              (\u0026CUR.stack[CUR.args - L + 1]),\n              (L - 1) * sizeof ( Long ) );\n\n    CUR.stack[ CUR.args-1 ] = K;\n  }\n\n\n[0] L is actually an unsigned long on x86. \n[1] L is user controled. \n[2] what if L is null then ?\n[3] will work fine with L null... \n[4] if L was null, then the sized passed to memmove is casted from an\nunsigned long to a signed integer (size_t) worthing\n111111111111111111111111111111 in binary, or 0x3fffffff. \n\n\nLet\u0027s now consider the third argument passed to memmove in [4]. This\nvalue is used as a counter in register ecx, resulting in the copy of a very\nlarge chunk of memory (0x3fffffff ~= 1Gb). At this time, the destination being\nsomewhere in the heap, the appliation will eventually fill the heap segment\nwith (unexpected) data, and the copy will fail when trying to write to the\nfirst non mapped address after the heap in the address space, generating a\nsegmentation fault. \n\nExperimentally, reaching this codepath has shown to be possible. \nThe values of the registers (in particular ecx and edi) at crash time are\ncoherent with our expectations and the explaination above :\n\nProgram received signal SIGSEGV, Segmentation fault. \n-------------------------------------------------------------------------[\nregs\n     eax:FFFFFFFC ebx:405B6FF4  ecx:3FF85061  edx:0807C844\neflags:00010216\n     esi:0826A000 edi:08269FFC  esp:BFFFDD18  ebp:BFFFDD58     eip:408EFA83\n     cs:0073  ds:007B  es:007B  fs:0000  gs:0033  ss:007B    o d I t s z\nA P c\n[007B:BFFFDD18]---------------------------------------------------------[stack]\nBFFFDD48 : E0 13 F9 FF  F4 6F 5B 40 - 44 C8 07 08  00 00 00 00\n.....o[@D....... \nBFFFDD38 : 00 00 00 00  00 00 00 00 - 01 00 00 00  0D 00 00 00\n................ \nBFFFDD28 : FC FF FF FF  AE 42 0F 40 - 44 C8 07 08  34 CA 07 08\n.....B.@D...4... \nBFFFDD18 : 26 00 00 00  09 69 0F 40 - 84 E1 07 08  88 E1 07 08\n\u0026....i.@........ \n[007B:0826A000]---------------------------------------------------------[ data]\n\u003cmemmove+35\u003e:    rep movs DWORD PTR es:[edi],DWORD PTR ds:[esi]\n\n\nArbitrary code execution would require to corrupt the heap with a bit more than\n1Gb of copied data without writting to invalid memory.

From our experience, they do not practice such a\n      thing but silently patch reported bugs instead. We hope this was\n      merely an exception. \n\n\n--[ Credits:\n    This vulnerability was discovered by Jonathan Brossard from Toucan System. \n\n--[ About Toucan System:\n",
