Subject Name:            sudo
Subject Summary:         Flexible Switch User Command
Subject Home:            http://www.sudo.ws/
Subject Versions:        * <= 1.6.8p1

Vulnerability Id:        CVE-2004-1051
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           local system
Attack Impact:           arbitrary code execution

Description:
    Liam Helmer discovered a design flaw in Sudo [0], a program used to
    control user privilege escalation. The Sudo function rebuild_env()
    fails to sufficiently clean potentially dangerous variables from
    the environment passed to the program to be executed. An attacker
    with Sudo access to a shell script that uses GNU Bash may therefore
    run arbitrary commands with other (including superuser) privileges.
