==========================================================================

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

- Ubuntu 23.04

- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in libvpx.

Software Description:
- libvpx: VP8 and VP9 video codec

Details:

It was discovered that libvpx did not properly handle certain malformed
