Red Hat: RHSA-2015:1627-01 Moderate: glibc Code Execution Risk

red hat
Calendar Grey August 17, 2015
Dist Redhat Esm H88
Newly released glibc updates for Red Hat 5 mitigate a security vulnerability classified as Moderate by the Red Hat Product Security team.
Updated glibc packages that fix one security issue are now available for Red Hat Linux 5

Solution

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

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258

Summary

The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly.
An invalid free flaw was found in glibc's getaddrinfo() function when used with the AI_IDN flag. A remote attacker able to make an application call this function could use this flaw to execute arbitrary code with the permissions of the user running the application. Note that this flaw only affected applications using glibc compiled with libidn support. (CVE-2013-7424)
All glibc users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
