Xconq is a multiple player strategy game available for many unix platforms. It contains a number of buffer overflow vulnerabilities including the ability to overflow stack buffers with either the DISPLAY or the USER environment variables. The Redhat Linux Xconq package installs the game with SGID 'games' privileges allowing an attacker to compromise the local 'games' group.
