Ubuntu Security Notice USN-7249-1
February 03, 2025

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

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

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

libvpx could be made to crash or run programs as your login if it
opened a specially crafted image file.

Software Description:
- libvpx: VP8 and VP9 video codec

Details:

Xiantong Hou discovered that libvpx would overflow when attempting to
allocate memory for very large images. If an application using libvpx
opened a specially crafted file, a remote attacker could possibly use
this issue to cause the application to crash, resulting in a denial
of service, or the execution of arbitrary code.

Update instructions:

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

Ubuntu 18.04 LTS
   libvpx5                         1.7.0-3ubuntu0.18.04.1+esm2
                                   Available with Ubuntu Pro
   vpx-tools                       1.7.0-3ubuntu0.18.04.1+esm2
                                   Available with Ubuntu Pro

Ubuntu 16.04 LTS
   libvpx3                         1.5.0-2ubuntu1.1+esm3
                                   Available with Ubuntu Pro
   vpx-tools                       1.5.0-2ubuntu1.1+esm3
                                   Available with Ubuntu Pro

Ubuntu 14.04 LTS

                                   Available with Ubuntu Pro
   vpx-tools                       1.3.0-2ubuntu0.1+esm3
                                   Available with Ubuntu Pro

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