Detail

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.

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"
