Details

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.

We apologize for the inconvenience.

Original advisory details:

Sebastian Krahmer discovered that DBus incorrectly handled environment
variables when running with elevated privileges. A local attacker could
