Description

Updated libvorbis packages that fix various security issues are now available for Red Hat Enterprise Linux 2.1.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The libvorbis packages contain runtime libraries for use in programs that support Ogg Vorbis. Ogg Vorbis is a fully open, non-proprietary, patent-and royalty-free, general-purpose compressed audio format.

Will Drewry of the Google Security Team reported several flaws in the way libvorbis processed audio data. An attacker could create a carefully crafted OGG audio file in such a way that it could cause an application linked with libvorbis to crash, or execute arbitrary code when it was opened. (CVE-2008-1419, CVE-2008-1420, CVE-2008-1423, CVE-2008-2009)

Moreover, additional OGG file sanity-checks have been added to prevent possible exploitation of similar issues in the future.

Users of libvorbis are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
