Ubuntu Security Notice USN-3664-1
May 30, 2018

apport vulnerability
==========================================================================

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

- - Ubuntu 18.04 LTS
- - Ubuntu 17.10
- - 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

Ubuntu 16.04 LTS:
  apport                          2.20.1-0ubuntu2.18

In general, a standard system update will make all the necessary changes.
