|Gentoo Linux Security Advisory
Title: Xvid: Array indexing vulnerabilities (GLSA 200708-02)
Date: August 08, 2007
Several array indexing vulnerabilities were discovered in Xvid, possibly allowing for the remote execution of arbitrary code.
Xvid is a popular open source video codec licensed under the GPL.
Vulnerable: < 1.1.3
Unaffected: >= 1.1.3
Architectures: All supported architectures
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.
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.
There is no known workaround at this time.
All Xvid users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/xvid-1.1.3"
