Ubuntu 8.04 LTS / 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : dbus regressions (USN-1576-2)

medium Nessus Plugin ID 62434

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected dbus and / or libdbus-1-3 packages.
