- ---------------------------------------------------------------------1. Summary:

Updated libvorbis packages to correct several 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1  - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386

3. Problem description:

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

Several flaws were found 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-2007-3106, CVE-2007-4029,
CVE-2007-4065, CVE-2007-4066)

Users of libvorbis are advised to upgrade to this updated package, which
contains backported patches that resolve these issues.

4. Solution:

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