Ubuntu 8.04 LTS / 9.10 / 10.04 LTS / 10.10 : logwatch vulnerability (USN-1078-1)

critical Nessus Plugin ID 52480

Language:

Synopsis

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

Description

Dominik George discovered that logwatch did not properly sanitize log file names that were passed to the shell as part of a command. If a remote attacker were able to generate specially crafted filenames (for example, via Samba logging), they could execute arbitrary code 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.

Solution

Update the affected logwatch package.
