Ubuntu Update for dbus USN-1576-2

Ubuntu Update for Linux kernel vulnerabilities USN-1576-2
Please Install the Updated Packages.
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 possibly exploit this flaw with a setuid binary and gain root privileges.
