CWE CWE-119
CAPEC
  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.
  • Overflow Binary Resource File
    An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process. This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow.
  • Buffer Overflow via Symbolic Links
    This type of attack leverages the use of symbolic links to cause buffer overflows. An attacker can try to create or manipulate a symbolic link file such that its contents result in out of bounds data. When the target software processes the symbolic link file, it could potentially overflow internal buffers with insufficient bounds checking.
  • Overflow Variables and Tags
    This type of attack leverages the use of tags or variables from a formatted configuration data to cause buffer overflow. The attacker crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.
  • Buffer Overflow via Parameter Expansion
    In this attack, the target software is given input that the attacker knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.
  • Buffer Overflow in an API Call
    This attack targets libraries or shared code modules which are vulnerable to buffer overflow attacks. An attacker who has access to an API may try to embed malicious code in the API function call and exploit a buffer overflow vulnerability in the function's implementation. All clients that make use of the code library thus become vulnerable by association. This has a very broad effect on security across a system, usually affecting more than one software process.
  • Buffer Overflow in Local Command-Line Utilities
    This attack targets command-line utilities available in a number of shells. An attacker can leverage a vulnerability found in a command-line utility to escalate privilege to root.

    description USN-2985-1 fixed vulnerabilities in the GNU C Library. The fix for CVE-2014-9761 introduced a regression which affected applications that use the libm library but were not fully restarted after the upgrade. This update removes the fix for CVE-2014-9761 and a future update will be provided to address this issue. We apologize for the inconvenience. Martin Carpenter discovered that pt_chown in the GNU C Library did not properly check permissions for tty files. A local attacker could use this to gain administrative privileges or expose sensitive information. (CVE-2013-2207, CVE-2016-2856) Robin Hack discovered that the Name Service Switch (NSS) implementation in the GNU C Library did not properly manage its file descriptors. An attacker could use this to cause a denial of service (infinite loop). (CVE-2014-8121) Joseph Myers discovered that the GNU C Library did not properly handle long arguments to functions returning a representation of Not a Number (NaN). An attacker could use this to cause a denial of service (stack exhaustion leading to an application crash) or possibly execute arbitrary code. (CVE-2014-9761) Arjun Shankar discovered that in certain situations the nss_dns code in the GNU C Library did not properly account buffer sizes when passed an unaligned buffer. An attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2015-1781) Sumit Bose and Lukas Slebodnik discovered that the Name Service Switch (NSS) implementation in the GNU C Library did not handle long lines in the files databases correctly. A local attacker could use this to cause a denial of service (application crash) or possibly execute arbitrary code. (CVE-2015-5277) Adam Nielsen discovered that the strftime function in the GNU C Library did not properly handle out-of-range argument data. An attacker could use this to cause a denial of service (application crash) or possibly expose sensitive information. (CVE-2015-8776) Hector Marco and Ismael Ripoll discovered that the GNU C Library allowed the pointer-guarding protection mechanism to be disabled by honoring the LD_POINTER_GUARD environment variable across privilege boundaries. A local attacker could use this to exploit an existing vulnerability more easily. (CVE-2015-8777) Szabolcs Nagy discovered that the hcreate functions in the GNU C Library did not properly check its size argument, leading to an integer overflow. An attacker could use to cause a denial of service (application crash) or possibly execute arbitrary code. (CVE-2015-8778) Maksymilian Arciemowicz discovered a stack-based buffer overflow in the catopen function in the GNU C Library when handling long catalog names. An attacker could use this to cause a denial of service (application crash) or possibly execute arbitrary code. (CVE-2015-8779) Florian Weimer discovered that the getnetbyname implementation in the GNU C Library did not properly handle long names passed as arguments. An attacker could use to cause a denial of service (stack exhaustion leading to an application crash). (CVE-2016-3075). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description The remote host is affected by the vulnerability described in GLSA-201602-02 (GNU C Library: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in the GNU C Library: The Google Security Team and Red Hat discovered a stack-based buffer overflow in the send_dg() and send_vc() functions due to a buffer mismanagement when getaddrinfo() is called with AF_UNSPEC (CVE-2015-7547). The strftime() function access invalid memory when passed out-of-range data, resulting in a crash (CVE-2015-8776). An integer overflow was found in the __hcreate_r() function (CVE-2015-8778). Multiple unbounded stack allocations were found in the catopen() function (CVE-2015-8779). Please review the CVEs referenced below for additional vulnerabilities that had already been fixed in previous versions of sys-libs/glibc, for which we have not issued a GLSA before. Impact : A remote attacker could exploit any application which performs host name resolution using getaddrinfo() in order to execute arbitrary code or crash the application. The other vulnerabilities can possibly be exploited to cause a Denial of Service or leak information. Workaround : A number of mitigating factors for CVE-2015-7547 have been identified. Please review the upstream advisory and references below.

    description Several vulnerabilities have been fixed in the GNU C Library, eglibc. The CVE-2015-7547 vulnerability listed below is considered to have critical impact. - CVE-2014-8121 Robin Hack discovered that the nss_files database did not correctly implement enumeration interleaved with name-based or ID-based lookups. This could cause the enumeration enter an endless loop, leading to a denial of service. - CVE-2015-1781 Arjun Shankar discovered that the _r variants of host name resolution functions (like gethostbyname_r), when performing DNS name resolution, suffered from a buffer overflow if a misaligned buffer was supplied by the applications, leading to a crash or, potentially, arbitrary code execution. Most applications are not affected by this vulnerability because they use aligned buffers. - CVE-2015-7547 The Google Security Team and Red Hat discovered that the eglibc host name resolver function, getaddrinfo, when processing AF_UNSPEC queries (for dual A/AAAA lookups), could mismanage its internal buffers, leading to a stack-based buffer overflow and arbitrary code execution. This vulnerability affects most applications which perform host name resolution using getaddrinfo, including system services. - CVE-2015-8776 Adam Nielsen discovered that if an invalid separated time value is passed to strftime, the strftime function could crash or leak information. Applications normally pass only valid time information to strftime; no affected applications are known. - CVE-2015-8777 Hector Marco-Gisbert reported that LD_POINTER_GUARD was not ignored for SUID programs, enabling an unintended bypass of a security feature. This update causes eglibc to always ignore the LD_POINTER_GUARD environment variable. - CVE-2015-8778 Szabolcs Nagy reported that the rarely-used hcreate and hcreate_r functions did not check the size argument properly, leading to a crash (denial of service) for certain arguments. No impacted applications are known at this time. - CVE-2015-8779 The catopen function contains several unbound stack allocations (stack overflows), causing it the crash the process (denial of service). No applications where this issue has a security impact are currently known. The following fixed vulnerabilities currently lack CVE assignment : - Joseph Myers reported that an integer overflow in the strxfrm can lead to heap-based buffer overflow, possibly allowing arbitrary code execution. In addition, a fallback path in strxfrm uses an unbounded stack allocation (stack overflow), leading to a crash or erroneous application behavior. - Kostya Serebryany reported that the fnmatch function could skip over the terminating NUL character of a malformed pattern, causing an application calling fnmatch to crash (denial of service). - Joseph Myers reported that the IO_wstr_overflow function, internally used by wide-oriented character streams, suffered from an integer overflow, leading to a heap-based buffer overflow. On GNU/Linux systems, wide-oriented character streams are rarely used, and no affected applications are known. - Andreas Schwab reported a memory leak (memory allocation without a matching deallocation) while processing certain DNS answers in getaddrinfo, related to the _nss_dns_gethostbyname4_r function. This vulnerability could lead to a denial of service. While it is only necessary to ensure that all processes are not using the old eglibc anymore, it is recommended to reboot the machines after applying the security upgrade.

    description According to the versions of the glibc packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - A stack overflow vulnerability was found in nan* functions that could cause applications, which process long strings with the nan function, to crash or, potentially, execute arbitrary code. (CVE-2014-9761) - It was found that out-of-range time values passed to the strftime() function could result in an out-of-bounds memory access. This could lead to application crash or, potentially, information disclosure. (CVE-2015-8776) - An integer overflow vulnerability was found in hcreate() and hcreate_r() functions which could result in an out-of-bounds memory access. This could lead to application crash or, potentially, arbitrary code execution. (CVE-2015-8778) - A stack based buffer overflow vulnerability was found in the catopen() function. An excessively long string passed to the function could cause it to crash or, potentially, execute arbitrary code. (CVE-2015-8779) - It was found that the dynamic loader did not sanitize the LD_POINTER_GUARD environment variable. An attacker could use this flaw to bypass the pointer guarding protection on set-user-ID or set-group-ID programs to execute arbitrary code with the permissions of the user running the application.

  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DSA-3481.NASL
    description Several vulnerabilities have been fixed in the GNU C Library, glibc. The first vulnerability listed below is considered to have critical impact. - CVE-2015-7547 The Google Security Team and Red Hat discovered that the glibc host name resolver function, getaddrinfo, when processing AF_UNSPEC queries (for dual A/AAAA lookups), could mismanage its internal buffers, leading to a stack-based buffer overflow and arbitrary code execution. This vulnerability affects most applications which perform host name resolution using getaddrinfo, including system services. - CVE-2015-8776 Adam Nielsen discovered that if an invalid separated time value is passed to strftime, the strftime function could crash or leak information. Applications normally pass only valid time information to strftime; no affected applications are known. - CVE-2015-8778 Szabolcs Nagy reported that the rarely-used hcreate and hcreate_r functions did not check the size argument properly, leading to a crash (denial of service) for certain arguments. No impacted applications are known at this time. - CVE-2015-8779 The catopen function contains several unbound stack allocations (stack overflows), causing it the crash the process (denial of service). No applications where this issue has a security impact are currently known. While it is only necessary to ensure that all processes are not using the old glibc anymore, it is recommended to reboot the machines after applying the security upgrade.

An excessively long string passed to the function could cause it to crash or, potentially, execute arbitrary code. (CVE-2015-8779) - It was found that the dynamic loader did not sanitize the LD_POINTER_GUARD environment variable. An attacker could use this flaw to bypass the pointer guarding protection on set-user-ID or set-group-ID programs to execute arbitrary code with the permissions of the user running the application. (CVE-2015-8777) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description This update for glibc fixes the following issues : - CVE-2015-7547: A stack-based buffer overflow in getaddrinfo allowed remote attackers to cause a crash or execute arbitrary code via crafted and timed DNS responses (bsc#961721) - CVE-2015-8777: Insufficient checking of LD_POINTER_GUARD environment variable allowed local attackers to bypass the pointer guarding protection of the dynamic loader on set-user-ID and set-group-ID programs (bsc#950944) - CVE-2015-8776: Out-of-range time values passed to the strftime function may cause it to crash, leading to a denial of service, or potentially disclosure information (bsc#962736) - CVE-2015-8778: Integer overflow in hcreate and hcreate_r could have caused an out-of-bound memory access. leading to application crashes or, potentially, arbitrary code execution (bsc#962737) - CVE-2014-9761: A stack overflow (unbounded alloca) could have caused applications which process long strings with the nan function to crash or, potentially, execute arbitrary code. (bsc#962738) - CVE-2015-8779: A stack overflow (unbounded alloca) in the catopen function could have caused applications which pass long strings to the catopen function to crash or, potentially execute arbitrary code. (bsc#962739) - CVE-2013-2207: pt_chown tricked into granting access to another users pseudo-terminal (bsc#830257) - CVE-2013-4458: Stack (frame) overflow in getaddrinfo() when called with AF_INET6 (bsc#847227) - CVE-2014-8121: denial of service issue in the NSS backends (bsc#918187) - bsc#920338: Read past end of pattern in fnmatch - CVE-2015-1781: buffer overflow in nss_dns (bsc#927080) The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
