Ubuntu 5.04 / 5.10 : gdm vulnerabilitiy (USN-278-1)

Low Nessus Plugin ID 21372


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


Marcus Meissner discovered a race condition in gdm's handling of the ~/.ICEauthority file permissions. A local attacker could exploit this to become the owner of an arbitrary file in the system. When getting control over automatically executed scripts (like cron jobs), the attacker could eventually leverage this flaw to execute arbitrary commands with 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.


Update the affected gdm package.
