RHEL 6 : glibc (RHSA-2012:1208)

medium Nessus Plugin ID 61691

Language:

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.

Solution

Update the affected packages.
