|
22 |
Background |
23 |
========== |

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" |
