 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.
