CVE-2013-6630

Publication date 18 November 2013

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.

The fix is to initialize huffval[].

mdeslaur

Although original report seems to indicate libjpeg6b isn't affected, that particular code is identical.
