Mandriva Linux Security Advisory 2013-162 - 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. 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. Various other issues were also addressed. The updated packages have been patched to correct these issues.

Mandriva Linux Security Advisory MDVSA-2013:162

_______________________________________________________________________

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.
