Re: Unreal engine updates and Battle Mages advisory
Luigi,
After seeing some doubt expressed by users in the Unreal community, I
tried your INI file test this morning on multiple Unreal Tournament
products and just now on America's Army 2.0. I confirmed crashes for UT,
UT2003 demo, and AA. UT2004 demo ran fine. Results are detailed a little
more below.
One question: Do you see the remote code execution as a possibility or
did you actually accomplish executing code in your tests? I'm trying to
clarify the exact level of threat to some users and they tend to take it
more seriously when it can be presented as "verified to be exploitable
for practical use not just DoS".
Results:
Unreal Tournament v451: Crashed with a GPF. Errors noted in log as follows:
