CWE-680 Sep 13, 2026
MKVToolNix through 101.0 Heap Buffer Overflow via avilib ODML Superindex Integer Wraparound
MKVToolNix through 101.0 contains a heap buffer overflow in the bundled avilib library's ODML superindex parser due to integer wraparound in 32-bit arithmetic. Attackers can craft a malicious AVI file with oversized entry counts that cause an undersized heap allocation, allowing a heap buffer overflow when the file is parsed with mkvmerge.
