Unreal Server Vulnerability Alert

Unreal Engine Heap Overflow:

A heap overflow has been found in the Unreal Engine that is exploitable against machines running many Unreal based games in server mode. Although we have no reports of exploits being used in the wild, it is believed that exploiting this vulnerability to remotely execute code is possible. We recommend that anyone serving one of the vulnerable games based on the Unreal Engine install patches as soon as they become available. Until patches are available, the only secure recourse is to block all UDP traffic to ports 7777 and 7787 (which will, effectively, keep you from acting as a game server). Limiting access to ports 7777 and 7787 to known IPs is not an effective defense because this is a UDP based attack and packets can be spoofed.
