Mandriva Linux Security Advisory 2013-284 - 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 or possibly execute arbitrary code via a long string, which triggers a heap-based buffer overflow. Stack-based buffer overflow in string/strcoll_l.c in the GNU C Library 2.17 and earlier allows context-dependent attackers to cause a denial of service or possibly execute arbitrary code via a long string that triggers a malloc failure and use of the alloca function. Multiple integer overflows in malloc/malloc.c in the GNU C Library (aka glibc or libc6) 2.18 and earlier allow context-dependent attackers to cause a denial of service via a large value to the aligned_alloc functions. A stack overflow flaw, which led to a denial of service (application crash), was found in the way glibc's getaddrinfo() function processed certain requests when called with AF_INET6. A similar flaw to this affects AF_INET6 rather than AF_UNSPEC. The PTR_MANGLE implementation in the GNU C Library (aka glibc or libc6) 2.4, 2.17, and earlier, and Embedded GLIBC 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. The updated packages have been patched to correct these issues.

Mandriva Linux Security Advisory MDVSA-2013:284
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : glibc
Date : November 25, 2013
Affected: Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities was found and corrected in glibc:

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).

Multiple integer overflows in malloc/malloc.c in the GNU C Library (aka
glibc or libc6) 2.18 and earlier allow context-dependent attackers to
cause a denial of service (heap corruption) via a large value to the
(1) pvalloc, (2) valloc, (3) posix_memalign, (4) memalign, or (5)
aligned_alloc functions (CVE-2013-4332).

A stack (frame) overflow flaw, which led to a denial of service
(application crash), was found in the way glibc's getaddrinfo()
function processed certain requests when called with AF_INET6. A
similar flaw to CVE-2013-1914, this affects AF_INET6 rather than
AF_UNSPEC (CVE-2013-4458).

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).

The updated packages have been patched to correct these issues.
