FFmpeg’s YUVCMP Blunder: Overflowing Into Chaos!
Beware of the FFmpeg yuvcmp tool’s kryptonite: integer overflow! When oversized width and height parameters meet, they cause a buffer size calculation calamity, leading to potential memory misadventures. It’s like trying to fit a sumo wrestler into a kiddie pool—overflow is inevitable. Keep your parameters in check to avoid a crash course in digital disaster!
Hot Take:
Who would’ve thought that a tool meant for comparing video frames could be so dangerous? This is one case where the only thing that should be overflowing is your popcorn bowl—not your memory allocation!
Key Points:
- FFmpeg’s yuvcmp utility is vulnerable to an integer overflow.
- Occurs when large width and height parameters are supplied.
- Can lead to denial of service (DoS) or potential heap corruption.
- Vulnerable versions are FFmpeg 7.0 to 8.0.
- Proof of concept demonstrates the overflow using excessive dimensions.
