apport vulnerabilities

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

- Ubuntu 15.04
- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS


Apport could be tricked into creating arbitrary files as an administrator,
resulting in privilege escalation.

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


Sander Bos discovered that Apport incorrectly handled permissions when
the system was configured to generate core dumps for setuid binaries. A
local attacker could use this issue to gain elevated privileges.

Philip Pettersson discovered that Apport contained race conditions
resulting core dumps to be generated with incorrect permissions in
arbitrary locations. A local attacker could use this issue to gain elevated
privileges. (CVE-2015-1325)

Update instructions:

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

Ubuntu 15.04:
  apport                          2.17.2-0ubuntu1.1

Ubuntu 14.10:
  apport                          2.14.7-0ubuntu8.5

Ubuntu 14.04 LTS:
  apport                          2.14.1-0ubuntu3.11

Ubuntu 12.04 LTS:
  apport                          2.0.1-0ubuntu17.9
