16 Synopsis
17 ========
18
19 The Crossfire game server is vulnerable to a Denial of Service and
20 potentially to the execution of arbitrary code.
21
22 Background
23 ==========
24
25 Crossfire is a cooperative multiplayer graphical adventure and
26 role-playing game. The Crossfire game server allows various compatible
27 clients to connect to participate in a cooperative game.

37 Description
38 ===========
39
40 Luigi Auriemma discovered a vulnerability in the Crossfire game server,
41 in the handling of the "oldsocketmode" option when processing overly
42 large requests.
43
44 Impact
45 ======
46
47 An attacker can set up a malicious Crossfire client that would send a
48 large request in "oldsocketmode", resulting in a Denial of Service on
49 the Crossfire server and potentially in the execution of arbitrary code
50 on the server with the rights of the game server.
51
52 Workaround
53 ==========
54
55 There is no known workaround at this time.
56
57 Resolution
58 ==========
59
60 All Crossfire server users should upgrade to the latest version:
61
62 # emerge --sync
63 # emerge --ask --oneshot --verbose
64 ">=games-server/crossfire-server-1.9.0"
