Red Hat Enterprise Linux Security Advisory RHSA-2009-1219-01 DoS Alert

red hat
Calendar Grey August 18, 2009
Scroller Redhat Esm H88
Essential security update for libvorbis addressing a denial of service flaw. Users of Red Hat systems are strongly recommended to upgrade.
Updated libvorbis packages that fix one security issue are now available for Red Hat Enterprise Linux 3, 4, and 5

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at

Summary

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.
An insufficient input validation flaw was found in the way libvorbis processes the codec file headers (static mode headers and encoding books) of the Ogg Vorbis audio file format (Ogg). A remote attacker could provide a specially-crafted Ogg file that would cause a denial of service (memory corruption and application crash) or, potentially, execute arbitrary code with the privileges of an application using the libvorbis library when opened by a victim. (CVE-2009-2663)
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.
