RHEL 4 / 5 / 6 : libvorbis (RHSA-2012:0136)
Critical Nessus Plugin ID 57957
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated libvorbis packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6.
The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
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.
A heap-based buffer overflow flaw was found in the way the libvorbis library parsed Ogg Vorbis media files. If a specially crafted Ogg Vorbis media file was opened by an application using libvorbis, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application.
Users of libvorbis should upgrade to these updated packages, which contain a backported patch to correct this issue. The desktop must be restarted (log out, then log back in) for this update to take effect.
SolutionUpdate the affected packages.
