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.

Author Note
seth-arnold The fix is to initialize huffval[].
mdeslaur Although original report seems to indicate libjpeg6b isn’t affected, that particular code is identical.
