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

Several security issues were fixed in libfs.

Ilja van Sprundel discovered multiple security issues in various X.org
libraries and components. An attacker could use these issues to cause
applications to crash, resulting in a denial of service, or possibly
execute arbitrary code.
