Gentoo Linux Security Advisory

Title: Crossfire server: Denial of Service and potential arbitrary code execution (GLSA 200604-11)
Severity: high
Exploitable: remote
Date: April 22, 2006
Bug(s): #126169
ID: 200604-11

Synopsis


The Crossfire game server is vulnerable to a Denial of Service and
potentially to the execution of arbitrary code.


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: games-server/crossfire-server
Vulnerable: < 1.9.0
Unaffected: >= 1.9.0
Architectures: All supported architectures


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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=games-server/crossfire-server-1.9.0"


References

CVE-2006-1010
