Unfortunately Epic games has been slow to respond or produce a fix of any kind for their customers & clients. As documented within the full advisory, Epic & its employees engaged PivX & its researchers in a variable game of 'cat & mouse' over the course of 3 months prior to this release. "Our goal at PivX is to work with committed vendors in creating fixes & pushing them to market in a timely manner. If raising public awareness helps to succeed that goal, then so be it." Says Geoff Shively, Chief Hacking Officer for PivX Solutions.
The full advisory also contains a link to a utility to verify how this affects your Unreal engine game.
