GLSA-201612-55 : libjpeg-turbo: User-assisted execution of arbitrary code

medium Nessus Plugin ID 96230

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201612-55 (libjpeg-turbo: User-assisted execution of arbitrary code)

The accelerated Huffman decoder was previously invoked if there were 128 bytes in the input buffer. However, it is possible to construct a JPEG image with Huffman blocks > 430 bytes in length. This release simply increases the minimum buffer size for the accelerated Huffman decoder to 512 bytes, which should accommodate any possible input.
Impact :

A remote attacker could coerce the victim to run a specially crafted image file resulting in the execution of arbitrary code.
Workaround :

There is no known workaround at this time.

Solution

All libjpeg-turbo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/libjpeg-turbo-1.5.0'
