Arbitrary code execution via ConvertFile buffer overflow
Published Jul 16, 2025 · Updated Apr 7, 2026
Buffer overflow in VideoPlayer.ocx 2.6 allows remote attackers to execute arbitrary code through a crafted ActiveX method argument. The CNA identifies ConvertFile(), while public exploit code overflows a .data buffer through SetText(), overwrites a pointer, and uses SetFontName() for a controlled memory write. Exploitation requires active interaction with hostile browser content and executes code in the current process context.
