CentOS Errata and Security Advisory CESA-2012:0136
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. (CVE-2012-0444)
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.
