ID CVE-2012-3406
Summary The vfprintf function in stdio-common/vfprintf.c in GNU C Library (aka glibc) 2.5, 2.12, and probably other versions does not "properly restrict the use of" the alloca function when allocating the SPECS array, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (crash) or possibly execute arbitrary code via a crafted format string using positional parameters and a large number of format specifiers, a different vulnerability than CVE-2012-3404 and CVE-2012-3405.

Impact:
Exploitability:
CWE CWE-264
CAPEC
  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The rhev-hypervisor5 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. It was discovered that the formatted printing functionality in glibc did not properly restrict the use of alloca(). This could allow an attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code using a format string flaw in an application, even though these protections are expected to limit the impact of such flaws to an application abort. (CVE-2012-3406) This updated package provides updated components that include fixes for various security issues. These issues have no security impact on Red Hat Enterprise Virtualization Hypervisor itself, however. The security fixes included in this update address the following CVE numbers : CVE-2012-3817 (bind issue) CVE-2012-3571 (dhcp issue) CVE-2012-2313 (kernel issue) CVE-2012-0441 (nss issue) CVE-2012-2337 and CVE-2012-3440 (sudo issues) CVE-2012-2625 (xen issue) Users of Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which fixes these issues.

  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2012-1098.NASL
    description Updated glibc packages that fix three security issues and one bug are now available for Red Hat Enterprise Linux 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. The glibc packages provide the standard C and standard math libraries used by multiple programs on the system. Without these libraries, the Linux system cannot function properly. Multiple errors in glibc's formatted printing functionality could allow an attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code using a format string flaw in an application, even though these protections are expected to limit the impact of such flaws to an application abort. (CVE-2012-3404, CVE-2012-3405, CVE-2012-3406) This update also fixes the following bug : * A programming error caused an internal array of nameservers to be only partially initialized when the /etc/resolv.conf file contained IPv6 nameservers. Depending on the contents of a nearby structure, this could cause certain applications to terminate unexpectedly with a segmentation fault. The programming error has been fixed, which restores proper behavior with IPv6 nameservers listed in the /etc/resolv.conf file. (BZ#837026) All users of glibc are advised to upgrade to these updated packages, which contain backported patches to fix these issues.

Note that this vulnerability is disputed by the library vendor. (CVE-2009-5064) - A remote code execution vulnerability exists in the glibc library due to an integer signedness error in the elf_get_dynamic_info() function when the '--verify' option is used. A remote attacker can exploit this by using a crafted ELF program with a negative value for a certain d_tag structure member in the ELF header. (CVE-2010-0830) - A flaw exists in OpenSSL due to a failure to properly prevent modification of the ciphersuite in the session cache when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled. A remote attacker can exploit this to force a downgrade to an unintended cipher by intercepting the network traffic to discover a session identifier. (CVE-2010-4180) - A flaw exists in OpenSSL due to a failure to properly validate the public parameters in the J-PAKE protocol when J-PAKE is enabled. A remote attacker can exploit this, by sending crafted values in each round of the protocol, to bypass the need for knowledge of the shared secret. (CVE-2010-4252) - A out-of-bounds memory error exists in OpenSSL that allows a remote attacker to cause a denial of service or possibly obtain sensitive information by using a malformed ClientHello handshake message. This is also known as the 'OCSP stapling vulnerability'. (CVE-2011-0014) - A flaw exists in the addmntent() function in the glibc library due to a failure to report the error status for failed attempts to write to the /etc/mtab file. A local attacker can exploit this to corrupt the file by using writes from a process with a small RLIMIT_FSIZE value. (CVE-2011-1089) - A flaw exists in the png_set_text_2() function in the file pngset.c in the libpng library due to a failure to properly allocate memory. An unauthenticated, remote attacker can exploit this, via a crafted text chunk in a PNG image file, to trigger a heap-based buffer overflow, resulting in denial of service or the execution of arbitrary code. (CVE-2011-3048) - A flaw exists in the DTLS implementation in OpenSSL due to performing a MAC check only if certain padding is valid. A remote attacker can exploit this, via a padding oracle attack, to recover the plaintext. (CVE-2011-4108) - A double-free error exists in OpenSSL when the X509_V_FLAG_POLICY_CHECK is enabled. A remote attacker can exploit this by triggering a policy check failure, resulting in an unspecified impact. (CVE-2011-4109) - A flaw exists in OpenSSL in the SSL 3.0 implementation due to improper initialization of data structures used for block cipher padding. A remote attacker can exploit this, by decrypting the padding data sent by an SSL peer, to obtain sensitive information. (CVE-2011-4576) - A denial of service vulnerability exists in OpenSSL when RFC 3779 support is enabled. A remote attacker can exploit this to cause an assertion failure, by using an X.509 certificate containing certificate extension data associated with IP address blocks or Autonomous System (AS) identifiers. (CVE-2011-4577) - A denial of service vulnerability exists in the RPC implementation in the glibc library due to a flaw in the svc_run() function. A remote attacker can exploit this, via large number of RPC connections, to exhaust CPU resources. (CVE-2011-4609) - A denial of service vulnerability exists in the Server Gated Cryptography (SGC) implementation in OpenSSL due to a failure to properly handle handshake restarts. A remote attacker can exploit this, via unspecified vectors, to exhaust CPU resources. (CVE-2011-4619) - A denial of service vulnerability exists in OpenSSL due to improper support of DTLS applications. A remote attacker can exploit this, via unspecified vectors related to an out-of-bounds read error. Note that this vulnerability exists because of an incorrect fix for CVE-2011-4108. (CVE-2012-0050) - A security bypass vulnerability exists in the glibc library due to an integer overflow condition in the vfprintf() function in file stdio-common/vfprintf.c. An attacker can exploit this, by using a large number of arguments, to bypass the FORTIFY_SOURCE protection mechanism, allowing format string attacks or writing to arbitrary memory. (CVE-2012-0864) - A denial of service vulnerability exists in the glibc library in the vfprintf() function in file stdio-common/vfprintf.c due to a failure to properly calculate a buffer length. An attacker can exploit this, via a format string that uses positional parameters and many format specifiers, to bypass the FORTIFY_SOURCE format-string protection mechanism, thus causing stack corruption and a crash. (CVE-2012-3404) - A denial of service vulnerability exists in the glibc library in the vfprintf() function in file stdio-common/vfprintf.c due to a failure to properly calculate a buffer length. An attacker can exploit this, via a format string with a large number of format specifiers, to bypass the FORTIFY_SOURCE format-string protection mechanism, thus triggering desynchronization within the buffer size handling, resulting in a segmentation fault and crash. (CVE-2012-3405) - A flaw exists in the glibc library in the vfprintf() function in file stdio-common/vfprintf.c due to a failure to properly restrict the use of the alloca() function when allocating the SPECS array. An attacker can exploit this, via a crafted format string using positional parameters and a large number of format specifiers, to bypass the FORTIFY_SOURCE format-string protection mechanism, thus triggering a denial of service or the possible execution of arbitrary code. (CVE-2012-3406) - A flaw exists in the glibc library due to multiple integer overflow conditions in the strtod(), strtof(), strtold(), strtod_l(), and other unspecified related functions. A local attacker can exploit these to trigger a stack-based buffer overflow, resulting in an application crash or the possible execution of arbitrary code. (CVE-2012-3480) - A privilege escalation vulnerability exists in the Virtual Machine Communication Interface (VMCI) due to a failure by control code to properly restrict memory allocation. A local attacker can exploit this, via unspecified vectors, to gain privileges. (CVE-2013-1406) - An error exists in the implementation of the Network File Copy (NFC) protocol. A man-in-the-middle attacker can exploit this, by modifying the client-server data stream, to cause a denial of service or the execution of arbitrary code. (CVE-2013-1659)

    description Updated glibc packages fix security vulnerabilities : Stephane Chazelas discovered that directory traversal issue in locale handling in glibc. glibc accepts relative paths with .. components in the LC_* and LANG variables. Together with typical OpenSSH configurations (with suitable AcceptEnv settings in sshd_config), this could conceivably be used to bypass ForceCommand restrictions (or restricted shells), assuming the attacker has sufficient level of access to a file system location on the host to create crafted locale definitions there (CVE-2014-0475). David Reid, Glyph Lefkowitz, and Alex Gaynor discovered a bug where posix_spawn_file_actions_addopen fails to copy the path argument (glibc bz #17048) which can, in conjunction with many common memory management techniques from an application, lead to a use after free, or other vulnerabilities (CVE-2014-4043). This update also fixes the following issues: x86: Disable x87 inline functions for SSE2 math (glibc bz #16510) malloc: Fix race in free() of fastbin chunk (glibc bz #15073) Tavis Ormandy discovered a heap-based buffer overflow in the transliteration module loading code. As a result, an attacker who can supply a crafted destination character set argument to iconv-related character conversation functions could achieve arbitrary code execution. This update removes support of loadable gconv transliteration modules. Besides the security vulnerability, the module loading code had functionality defects which prevented it from working for the intended purpose (CVE-2014-5119). Adhemerval Zanella Netto discovered out-of-bounds reads in additional code page decoding functions (IBM933, IBM935, IBM937, IBM939, IBM1364) that can be used to crash the systems, causing a denial of service conditions (CVE-2014-6040). The function wordexp() fails to properly handle the WRDE_NOCMD flag when processing arithmetic inputs in the form of '$((... ))' where '...' can be anything valid. The backticks in the arithmetic epxression are evaluated by in a shell even if WRDE_NOCMD forbade command substitution. This allows an attacker to attempt to pass dangerous commands via constructs of the above form, and bypass the WRDE_NOCMD flag. This update fixes the issue (CVE-2014-7817). The vfprintf function in stdio-common/vfprintf.c in GNU C Library (aka glibc) 2.5, 2.12, and probably other versions does not properly restrict the use of the alloca function when allocating the SPECS array, which allows context-dependent attackers to bypass the FORTIFY_SOURCE format-string protection mechanism and cause a denial of service (crash) or possibly execute arbitrary code via a crafted format string using positional parameters and a large number of format specifiers (CVE-2012-3406). The nss_dns implementation of getnetbyname could run into an infinite loop if the DNS response contained a PTR record of an unexpected format (CVE-2014-9402). Also glibc lock elision (new feature in glibc 2.18) has been disabled as it can break glibc at runtime on newer Intel hardware (due to hardware bug) Under certain conditions wscanf can allocate too little memory for the to-be-scanned arguments and overflow the allocated buffer (CVE-2015-1472). The incorrect use of '__libc_use_alloca (newsize)' caused a different (and weaker) policy to be enforced which could allow a denial of service attack (CVE-2015-1473).

CVE-2012-4412 Integer overflow in the strcoll and wcscoll functions allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string, which triggers a heap-based buffer overflow. CVE-2012-4424 Stack-based buffer overflow in the strcoll and wcscoll functions allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string that triggers a malloc failure and use of the alloca function. CVE-2013-0242 Buffer overflow in the extend_buffers function in the regular expression matcher allows context-dependent attackers to cause a denial of service (memory corruption and crash) via crafted multibyte characters. CVE-2013-1914 CVE-2013-4458 Stack-based buffer overflow in the getaddrinfo function allows remote attackers to cause a denial of service (crash) via a hostname or IP address that triggers a large number of domain conversion results. CVE-2013-4237 readdir_r allows context-dependent attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a malicious NTFS image or CIFS service. CVE-2013-4332 Multiple integer overflows in malloc/malloc.c allow context-dependent attackers to cause a denial of service (heap corruption) via a large value to the pvalloc, valloc, posix_memalign, memalign, or aligned_alloc functions. CVE-2013-4357 The getaliasbyname, getaliasbyname_r, getaddrinfo, getservbyname, getservbyname_r, getservbyport, getservbyport_r, and glob functions do not properly limit stack allocation, which allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code. CVE-2013-4788 When the GNU C library is statically linked into an executable, the PTR_MANGLE implementation does not initialize the random value for the pointer guard, so that various hardening mechanisms are not effective. CVE-2013-7423 The send_dg function in resolv/res_send.c does not properly reuse file descriptors, which allows remote attackers to send DNS queries to unintended locations via a large number of requests that trigger a call to the getaddrinfo function. CVE-2013-7424 The getaddrinfo function may attempt to free an invalid pointer when handling IDNs (Internationalised Domain Names), which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code. CVE-2014-4043 The posix_spawn_file_actions_addopen function does not copy its path argument in accordance with the POSIX specification, which allows context-dependent attackers to trigger use-after-free vulnerabilities.

    title Debian DSA-3169-1 : eglibc - security update
  • NASL family Oracle Linux Local Security Checks
    NASL id ORACLELINUX_ELSA-2012-1098.NASL
    description From Red Hat Security Advisory 2012:1098 : Updated glibc packages that fix three security issues and one bug are now available for Red Hat Enterprise Linux 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. The glibc packages provide the standard C and standard math libraries used by multiple programs on the system. Without these libraries, the Linux system cannot function properly. Multiple errors in glibc's formatted printing functionality could allow an attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code using a format string flaw in an application, even though these protections are expected to limit the impact of such flaws to an application abort. (CVE-2012-3404, CVE-2012-3405, CVE-2012-3406) This update also fixes the following bug : * A programming error caused an internal array of nameservers to be only partially initialized when the /etc/resolv.conf file contained IPv6 nameservers. Depending on the contents of a nearby structure, this could cause certain applications to terminate unexpectedly with a segmentation fault. The programming error has been fixed, which restores proper behavior with IPv6 nameservers listed in the /etc/resolv.conf file. (BZ#837026) All users of glibc are advised to upgrade to these updated packages, which contain backported patches to fix these issues.
