Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 / 9.10 : samba vulnerability (USN-893-1)

medium Nessus Plugin ID 44336

Language:

Synopsis

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

Description

Ronald Volgers discovered that the mount.cifs utility, when installed as a setuid program, suffered from a race condition when verifying user permissions. A local attacker could trick samba into mounting over arbitrary locations, 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 packages.
