NVD Description

Note: Versions mentioned in the description apply only to the upstream libjpeg-turbo-static package and not the libjpeg-turbo-static package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The get_dht function in jdmarker.c in libjpeg-turbo through 1.3.0, as used in Google Chrome before 31.0.1650.48 and other products, does not set all elements of a certain Huffman value array during the reading of segments that follow Define Huffman Table (DHT) JPEG markers, which allows remote attackers to obtain sensitive information from uninitialized memory locations via a crafted JPEG image.
