Crucial glibc vulnerability patch released for various Red Hat Enterprise Linux versions countering severe security issues.
Updated glibc packages that fix one security issue are now available for Red Hat Enterprise Linux 5.6 Long Life, Red Hat Enterprise Linux 5.9 Extended Update Support, Red Hat Enter...

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258

Summary

The glibc packages contain the standard C libraries used by multiple programs on the system. These packages contain the standard C and the standard math libraries. Without these two libraries, a Linux system cannot function properly.
An off-by-one heap-based buffer overflow flaw was found in glibc's internal __gconv_translit_find() function. An attacker able to make an application call the iconv_open() function with a specially crafted argument could possibly use this flaw to execute arbitrary code with the privileges of that application. (CVE-2014-5119)
All glibc users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
