libjpeg security update

CentOS Errata and Security Advisory CESA-2013:1803

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.
