 Package : libjpeg
 Date    : November 21, 2013
 Affected: Enterprise Server 5.0
 _______________________________________________________________________

 Problem Description:

 Updated libjpeg packages fix security vulnerabilities:
 
 A Heap-based buffer overflow was found in the way libjpeg-turbo
 decompressed certain corrupt JPEG images in which the component
 count was erroneously set to a large value. An attacker could create
 a specially-crafted JPEG image that, when opened, could cause an
 application using libpng to crash or, possibly, execute arbitrary
 code with the privileges of the user running the application
 (CVE-2012-2806).
 
 libjpeg 6b and libjpeg-turbo will use uninitialized memory when
 decoding images with missing SOS data for the luminance component
 (Y) in presence of valid chroma data (Cr, Cb) (CVE-2013-6629).
 
 libjpeg-turbo will use uninitialized memory when handling Huffman
 tables (CVE-2013-6630).
