| Doc Text: |
A flaw was found in MKVToolNix. An attacker can exploit this vulnerability by crafting a malicious AVI (Audio Video Interleave) file. When the mkvmerge tool processes this file, an integer wraparound in the bundled avilib library's ODML (OpenDML) superindex parser leads to an undersized memory allocation. This heap buffer overflow can result in arbitrary code execution or a denial of service.
