libvpx vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS

Summary:

libvpx could be made to crash or run programs if it received specially
crafted input.

Software Description:
- libvpx: VP8 and VP9 video codec

Details:

It was discovered that libvpx did not properly handle certain malformed
media files. If an application using libvpx opened a specially crafted

execute arbitrary code. Ubuntu 22.04 LTS, Ubuntu 20.04 LTS, Ubuntu 18.04
LTS, and Ubuntu 16.04 LTS were previously addressed in USN-6403-1,
USN-6403-2, and USN-6403-3. This update addresses the issue in Ubuntu 14.04

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

Ubuntu 14.04 LTS
   libvpx1                         1.3.0-2ubuntu0.1~esm3
                                   Available with Ubuntu Pro
