FreeBSD : zgv, xzgv -- heap overflow vulnerability (a813a219-d2d4-11da-a672-000e0c2e438a)

This script is Copyright (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

Gentoo reports :

Andrea Barisani of Gentoo Linux discovered xzgv and zgv allocate
insufficient memory when rendering images with more than 3 output
components, such as images using the YCCK or CMYK colour space. When
xzgv or zgv attempt to render the image, data from the image overruns
a heap allocated buffer.

An attacker may be able to construct a malicious image that executes
arbitrary code with the permissions of the xzgv or zgv user when
attempting to render the image.
