Crossfire is a cooperative multiplayer graphical adventure and role-playing game. The Crossfire game server allows various compatible clients to connect to participate in a cooperative game.
Luigi Auriemma discovered a vulnerability in the Crossfire game server, in the handling of the "oldsocketmode" option when processing overly large requests.
An attacker can set up a malicious Crossfire client that would send a large request in "oldsocketmode", resulting in a Denial of Service on the Crossfire server and potentially in the execution of arbitrary code on the server with the rights of the game server.
There is no known workaround at this time.
All Crossfire server users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=games-server/crossfire-server-1.9.0"
