glibc security update :

CVE-2012-4412 glibc: strcoll() integer overflow leading to buffer overflow CVE-2012-4424 glibc: alloca() stack overflow in the strcoll() interface CVE-2013-1914 glibc: Stack (frame) overflow in getaddrinfo() when processing entry mapping to long list of address structures CVE-2013-2207 glibc (pt_chown): Improper pseudotty ownership and permissions changes when granting access to the slave pseudoterminal CVE-2013-4237 glibc: Buffer overwrite when using readdir_r on file systems returning file names longer than NAME_MAX characters

Fix for CVE-2013-2207 may break chroots if their devpts was not mounted correctly. Fix is to mount the devpts correctly with gid=5.

This glibc update fixes a critical privilege escalation problem and the following security and non security issues :

  - bnc#892073: An off-by-one error leading to a heap-based     buffer overflow was found in __gconv_translit_find(). An     exploit that targets the problem is publicly available.
    (CVE-2014-5119)

The remote NewStart CGSL host, running version MAIN 5.04, has glibc packages installed that are affected by multiple vulnerabilities:

  - elf/dl-load.c in ld.so in the GNU C Library (aka glibc     or libc6) through 2.11.2, and 2.12.x through 2.12.1,     does not properly handle a value of $ORIGIN for the     LD_AUDIT environment variable, which allows local users     to gain privileges via a crafted dynamic shared object     (DSO) located in an arbitrary directory. (CVE-2010-3847)

  - ld.so in the GNU C Library (aka glibc or libc6) before     2.11.3, and 2.12.x before 2.12.2, does not properly     restrict use of the LD_AUDIT environment variable to     reference dynamic shared objects (DSOs) as audit     objects, which allows local users to gain privileges by     leveraging an unsafe DSO located in a trusted library     directory, as demonstrated by libpcprofile.so.
    (CVE-2010-3856)

  - Integer overflow in string/strcoll_l.c in the GNU C     Library (aka glibc or libc6) 2.17 and earlier 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-2012-4412)

  - Stack-based buffer overflow in string/strcoll_l.c in the     GNU C Library (aka glibc or libc6) 2.17 and earlier     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-2012-4424)

  - A flaw was found in the regular expression matching     routines that process multibyte character input. If an     application utilized the glibc regular expression     matching mechanism, an attacker could provide specially-     crafted input that, when processed, would cause the     application to crash. (CVE-2013-0242)

  - It was found that getaddrinfo() did not limit the amount     of stack memory used during name resolution. An attacker     able to make an application resolve an attacker-     controlled hostname or IP address could possibly cause     the application to exhaust all stack memory and crash.
    (CVE-2013-1914, CVE-2013-4458)

  - pt_chown in GNU C Library (aka glibc or libc6) before     2.18 does not properly check permissions for tty files,     which allows local users to change the permission on the     files and obtain access to arbitrary pseudo-terminals by     leveraging a FUSE file system. (CVE-2013-2207)

  - An out-of-bounds write flaw was found in the way the     glibc's readdir_r() function handled file system entries     longer than the NAME_MAX character constant. A remote     attacker could provide a specially crafted NTFS or CIFS     file system that, when processed by an application using     readdir_r(), would cause that application to crash or,     potentially, allow the attacker to execute arbitrary     code with the privileges of the user running the     application. (CVE-2013-4237)

  - Multiple integer overflow flaws, leading to heap-based     buffer overflows, were found in glibc's memory allocator     functions (pvalloc, valloc, and memalign). If an     application used such a function, it could cause the     application to crash or, potentially, execute arbitrary     code with the privileges of the user running the     application. (CVE-2013-4332)

  - The PTR_MANGLE implementation in the GNU C Library (aka     glibc or libc6) 2.4, 2.17, and earlier, and Embedded     GLIBC (EGLIBC) does not initialize the random value for     the pointer guard, which makes it easier for context-     dependent attackers to control execution flow by     leveraging a buffer-overflow vulnerability in an     application and using the known zero value pointer guard     to calculate a pointer address. (CVE-2013-4788)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
