Background ========= 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. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 games-server/crossfire-server < 1.9.0 > = 1.9.0 Description ========== Luigi Auriemma discovered a vulnerability in the Crossfire game server, in the handling of the "oldsocketmode" option when processing overly large requests. Impact ===== 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. Workaround ========= There is no known workaround at this time. Resolution ========= All Crossfire server users should upgrade to the latest version: # emerge --sync #emerge --ask --oneshot --verbose "> =games-server/crossfire-server-1.9.0" References ========= [ 1 ] CVE-2006-1010 https://www.cve.org/CVERecord?id=CVE-2006-1010 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200604-11 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
