The attached testcase was found by fuzzing packed PE files, I suspect it was packed using "Yoda's protector". This vulnerability is obviously exploitable for remote code execution as NT AUTHORITY\SYSTEM on all systems using Kaspersky Antivirus.

(bb8.ff0): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.

What does it do with that value once it's loaded?

Where does that pointer come from?

Directly from the input file, so this is obviously exploitable for remote code execution as NT AUTHORITY\SYSTEM.
