Ubuntu 8.04 LTS / 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : sudo vulnerability (USN-1442-1)

high Nessus Plugin ID 59170

Synopsis

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

Description

It was discovered that sudo incorrectly handled network masks when using Host and Host_List. A local user who is listed in sudoers may be allowed to run commands on unintended hosts when IPv4 network masks are used to grant access. A local attacker could exploit this to bypass intended access restrictions. Host and Host_List are not used in the default installation of Ubuntu.

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 sudo and / or sudo-ldap packages.
