Synopsis
========
Several array indexing vulnerabilities were discovered in Xvid,
possibly allowing for the remote execution of arbitrary code.
Background
==========
Xvid is a popular open source video codec licensed under the GPL.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/xvid < 1.1.3 >= 1.1.3
Description
===========
Trixter Jack discovered an array indexing error in the
get_intra_block() function in the file src/bitstream/mbcoding.c. The
get_inter_block_h263() and get_inter_block_mpeg() functions in the same
file were also reported as vulnerable.
Impact
======
An attacker could exploit these vulnerabilities to execute arbitrary
code by tricking a user or automated system into processing a malicious
video file with an application that makes use of the Xvid library.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Xvid users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/xvid-1.1.3"
References
