    Synopsis
    ========
    
    Multiple vulnerabilities have been found in sudo, the worst of which
    could result in privilege escalation.
    
    Background
    ==========
    
    sudo (su "do") allows a system administrator to delegate authority to
    give certain users (or groups of users) the ability to run some (or
    all) commands as root or another user while providing an audit trail of
    the commands and their arguments.
