The remote Red Hat host is missing one or more security updates.
Updated libvpx packages that fix one security issue are now available
for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having
moderate 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 libvpx packages provide the VP8 SDK, which allows the encoding and
decoding of the VP8 video codec, commonly used with the WebM
multimedia container file format.
An integer overflow flaw, leading to arbitrary memory writes, was
found in libvpx. An attacker could create a specially crafted video
encoded using the VP8 codec that, when played by a victim with an
application using libvpx (such as Totem), would cause the application
to crash or, potentially, execute arbitrary code. (CVE-2010-4203)
All users of libvpx are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. After
installing the update, all applications using libvpx must be restarted
for the changes to take effect.
