===========================================================
Ubuntu Security Notice USN-1015-1          November 10, 2010
libvpx vulnerability
CVE-2010-4203
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 10.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 10.10:
  libvpx0                         0.9.2-1ubuntu0.1

In general, a standard system update will make all the necessary changes.

Details follow:

Christoph Diehl discovered that libvpx did not properly perform bounds
checking. If an application using libvpx opened a specially crafted
WebM file, an attacker could cause a denial of service or possibly execute
code as the user invoking the program.
