Certain versions of Unixware ship with a version of xlock which is vulnerable to a buffer overflow attack. The xlock(1) program locks the local X display until a username and password are entered. In this instance a user can provide an overly long username and overflow a buffer in xlock(1). Given that xlock(1) runs SUID root this will result in a root compromise.
