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

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

Summary:

Apport could be tricked into causing a denial of service or escalate
privileges.

Software Description:

certain files are missing from /proc. A local attacker could possibly use
this issue to cause a denial of service, gain root privileges, or escape
from containers.
