 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.
