DESCRIPTION:
Luigi Auriemma has reported a vulnerability in Unreal Tournament 3,
which can be exploited by malicious people to cause a DoS (Denial of
Service).

The vulnerability is caused due to the use of uninitialized values
when handling "STEAMBLOB" commands, which can be exploited to cause
an invalid memory access and crash the server by sending a specially
crafted UDP packet.

The vulnerability is reported in version 2.1 (aka 3809). Other
versions may also be affected.

SOLUTION:
Use in trusted network environments only.
