USN-1953-1: polkit vulnerability

18 September 2013

polkit could be tricked into giving out improper authorization.



  • policykit-1 - framework for managing administrative policies and privileges


It was discovered that polkit didn't allow applications to use the pkcheck
tool in a way which prevented a race condition in the UID lookup. A local
attacker could use this flaw to possibly escalate privileges.

Update instructions

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

Ubuntu 13.04
Ubuntu 12.10
Ubuntu 12.04
Ubuntu 10.04

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