Description:
Luigi Auriemma has reported two vulnerabilities in Soldier of Fortune II, which can be exploited by malicious people to cause a DoS (Denial of Service).
1) Some boundary errors in the communication handling can be exploited by sending an overly long query or response to a vulnerable game server or client e.g. browsing the online server list.
Successful exploitation crashes a vulnerable server or client, but can reportedly not be exploited for execution of arbitrary code.
2) An error in the communication handling can be exploited to crash a vulnerable server by sending a specially crafted UDP datagram with an overly large "cl_guid" value.
The vulnerabilities have been reported in version 1.03 gold. Other versions may also be affected.
Solution:
Servers:
Grant only trusted clients access to games.
Clients:
Connect to trusted servers only and don't use the online server list.
