Unixware SCOhelp HTTP Server Format String Vulnerability

SCO Unixware 7 default installation includes scohelp, an http server that listens on port 457/tcp and allows access to manual pages and other documentation files. The search CGI script provided for that purpose has a vulnerability that could allow any remote attacker to execute arbitrary code on the vulnerable machine with privileges of user "nobody". This poses a threat that could result in the remote compromise of the vulnerable host and provide a staging point from where an attacker could escalate privileges.
