red hat
Calendar Grey December 9, 2013
Dist Redhat Esm H88
Red Hat has announced enhancements to its libjpeg-turbo packages aimed at addressing several concerns deemed of moderate severity. Delve into the specifics.
Updated libjpeg-turbo packages that fix two security issues are now available for Red Hat Enterprise Linux 6

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/site/articles/11258

Summary

The libjpeg-turbo package contains a library of functions for manipulating JPEG images. It also contains simple client programs for accessing the libjpeg functions.
An uninitialized memory read issue was found in the way libjpeg-turbo decoded images with missing Start Of Scan (SOS) JPEG markers or Define Huffman Table (DHT) JPEG markers. A remote attacker could create a specially crafted JPEG image that, when decoded, could possibly lead to a disclosure of potentially sensitive information. (CVE-2013-6629, CVE-2013-6630)
All libjpeg-turbo users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
