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

- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Apport could be made to crash or overwrite files as an administrator.

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

Details:

Halfdog discovered that Apport incorrectly handled kernel crash dump files.
A local attacker could use this issue to cause a denial of service, or
possibly elevate privileges. The default symlink protections for affected
releases should reduce the vulnerability to a denial of service.

Update instructions:

package versions:

Ubuntu 15.04:
  apport                          2.17.2-0ubuntu1.5

Ubuntu 12.04 LTS:
  apport                          2.0.1-0ubuntu17.10

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