RHEL 6 : glibc (RHSA-2012:1208)

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated glibc packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

The glibc packages provide the standard C and standard math libraries
used by multiple programs on the system. Without these libraries, the
Linux system cannot function properly.

Multiple integer overflow flaws, leading to stack-based buffer
overflows, were found in glibc's functions for converting a string to
a numeric representation (strtod(), strtof(), and strtold()). If an
application used such a function on attacker controlled input, it
could cause the application to crash or, potentially, execute
arbitrary code. (CVE-2012-3480)

All users of glibc are advised to upgrade to these updated packages,
which contain a backported patch to correct these issues.
