CVE-2024-41217Public exploitNetwork attack vector

Process crash via unchecked Matroska lace index

Published Nov 14, 2024 · Updated Nov 15, 2024

Heap-based buffer overflow in tsMuxer nightly-2024-05-10-02-00-45 allows remote attackers to crash the process with a crafted MKV file. MatroskaDemuxer::matroska_parse_block writes lace_size[n] without confirming that the input-derived index remains below the allocated lace count. A user must open or process the file; the demonstrated consequence is a process abort, with no reported data disclosure or code execution.
