How to fix?

Upgrade Ubuntu:12.04 sudo to version 1.8.3p1-1ubuntu3.6 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream sudo package and not the sudo package as distributed by Ubuntu. See How to fix? for Ubuntu:12.04 relevant fixed versions and status.

Sudo 1.6.9 before 1.8.5, when env_reset is disabled, does not properly check environment variables for the env_delete restriction, which allows local users with sudo permissions to bypass intended command restrictions via a crafted environment variable.
