Mandriva Linux Security Advisory MDVSA-2013:162
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : glibc
Date : May 7, 2013
Affected: Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been discovered and corrected in glibc:

Integer overflow in the vfprintf function in stdio-common/vfprintf.c
in glibc 2.14 and other versions allows context-dependent attackers to
bypass the FORTIFY_SOURCE protection mechanism, conduct format string
attacks, and write to arbitrary memory via a large number of arguments
(CVE-2012-0864).

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).

Multiple integer overflows in the (1) strtod, (2) strtof, (3) strtold,
(4) strtod_l, and other unspecified related functions in stdlib in
GNU C Library (aka glibc or libc6) 2.16 allow local users to cause a
denial of service (application crash) and possibly execute arbitrary
code via a long string, which triggers a stack-based buffer overflow
(CVE-2012-3480).

Buffer overflow in the extend_buffers function in the regular
expression matcher (posix/regexec.c) in glibc, possibly 2.17 and
earlier, allows context-dependent attackers to cause a denial of
service (memory corruption and crash) via crafted multibyte characters
(CVE-2013-0242).

Stack-based buffer overflow in the getaddrinfo function in
sysdeps/posix/getaddrinfo.c in GNU C Library (aka glibc or libc6)
2.17 and earlier allows remote attackers to cause a denial of service
(crash) via a (1) hostname or (2) IP address that triggers a large
number of domain conversion results (CVE-2013-1914).

The updated packages have been patched to correct these issues.
