The libjpeg 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 decoded images with missing Start Of Scan 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. All libjpeg users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
