Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : shadow vulnerability (USN-695-1)
high Nessus Plugin ID 37654
Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
Paul Szabo discovered a race condition in login. While setting up tty permissions, login did not correctly handle symlinks. If a local attacker were able to gain control of the system utmp file, they could cause login to change the ownership and permissions on arbitrary files, leading to a root privilege escalation.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 login and / or passwd packages.See Also
