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

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

- Ubuntu 18.04 LTS

- Ubuntu 16.04 LTS

Summary:

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

Software Description:
- apport: automatically generate crash reports for debugging

Details:

Sander Bos discovered that Apport incorrectly handled core dumps when
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.

Update instructions:

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

Ubuntu 18.04 LTS:
apport 2.20.9-0ubuntu7.1

Ubuntu 17.10:
apport 2.20.7-0ubuntu3.9
