Scroller Redhat
Red Hat has released an advisory about a moderate severity integer overflow vulnerability in lzo. Users should review the advisory and update quickly to protect system integrity
Updated lzo packages that fix one security issue are now available for Red Hat Enterprise Linux 6 and 7

Solution

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

LZO is a portable lossless data compression library written in ANSI C.
An integer overflow flaw was found in the way the lzo library decompressed certain archives compressed with the LZO algorithm. An attacker could create a specially crafted LZO-compressed input that, when decompressed by an application using the lzo library, would cause that application to crash or, potentially, execute arbitrary code. (CVE-2014-4607)
Red Hat would like to thank Don A. Bailey from Lab Mouse Security for reporting this issue.
All lzo users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. For the update to take effect, all services linked to the lzo library must be restarted or the system rebooted.
