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.
