April 16, 2015

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

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

– Ubuntu 14.10
– Ubuntu 14.04 LTS

Summary:

Apport could be tricked into running programs as an administrator.

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

Details:

USN-2569-1 fixed a vulnerability in Apport. Tavis Ormandy discovered that
the fixed packages were still vulnerable to a privilege escalation attack.
This update completely disables crash report handling for containers until
a more complete solution is available.

Original advisory details:

Stéphane Graber and Tavis Ormandy independently discovered that Apport
incorrectly handled the crash reporting feature. A local attacker could use
this issue to gain elevated privileges.

Update instructions:

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

Ubuntu 14.10:
apport 2.14.7-0ubuntu8.4

Ubuntu 14.04 LTS:
apport 2.14.1-0ubuntu3.10

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