Ubuntu Security Notice 1576-2 - USN-1576-1 fixed vulnerabilities in DBus. The update caused a regression for certain services launched from the activation helper, and caused an unclean shutdown on upgrade. This update fixes the problem.

A local attacker could possibly exploit this flaw with a setuid binary and gain root privileges. Various other issues were also addressed.
