Ubuntu 12.10 : pam-xdg-support vulnerability (USN-1766-1)

High Nessus Plugin ID 65608


The remote Ubuntu host is missing a security-related patch.


Zbigniew Tenerowicz and Sebastian Krzyszkowiak discovered that pam-xdg-support incorrectly handled the PATH environment variable. A local attacker could use this issue in combination with sudo to possibly escalate 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.


Update the affected libpam-xdg-support package.
