libwebp vulnerability
==========================================================================

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

- Ubuntu 23.04
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

libwebp could be made to crash or run programs if it opened a specially
crafted file.

Software Description:
- libwebp: Lossy compression of digital photographic images

Details:

It was discovered that libwebp incorrectly handled certain malformed
images.  If a user or automated system were tricked into opening a
specially crafted image file, a remote attacker could use this issue to
cause libwebp to crash, resulting in a denial of service, or possibly
execute arbitrary code.

Update instructions:

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