libvorbis security update

CentOS Errata and Security Advisory CESA-2007:0912-01

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.
