Ubuntu 11.10 : lightdm vulnerability (USN-1399-2)

Low Nessus Plugin ID 58341


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


Ryan Lortie discovered that a guest session script bundled in the Light Display Manager package improperly cleaned out certain guest session files. A local attacker could use this issue to delete arbitrary files.

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 lightdm package.
