Description:
Luigi Auriemma has reported some vulnerabilities in Halo: Combat Evolved, which can be exploited by malicious people to cause a DoS (Denial of Service).
1) Two vulnerabilities are caused due to errors in the communication handling. These can be exploited to cause a vulnerable service to enter an infinite loop and consume a large amount of CPU resources by sending a specially crafted packet to the server.
2) The vulnerability is caused due to the server sending packets continuously to a client after a successful handshake has been performed. This can be exploited to consume network bandwidth and large amounts of memory by sending specially crafted packets to an affected server.
The vulnerabilities are reported in version 1.07 and prior.
Solution:
Host games on a trusted network only.
