demux/mkv/mkv.hpp in the MKV demuxer plugin in VideoLAN VLC media player 1.1.6.1 and earlier allows remote attackers to cause a denial of service (crash) and execute arbitrary commands via a crafted MKV (WebM or Matroska) file that triggers memory corruption, related to "class mismatching" and the MKV_IS_ID macro.

Security readout for executives and security teams

A malicious video file could crash older VLC media player versions or potentially run commands on the user’s machine. The main business risk is users opening untrusted MKV, WebM, or Matroska files on endpoints with VLC 1.1.6.1 or earlier. Exposure is most likely on legacy desktops, media workstations, or servers using VideoLAN VLC media player 1.1.6.1 or earlier, especially where users process externally supplied media files. Prioritize remediation where legacy VLC exists on user workstations or media-processing systems. The issue is old, but potential command execution from a file-open workflow makes unmanaged legacy installs a meaningful endpoint risk. Mitigation focus: Identify and remove or update VLC 1.1.6.1 and earlier.; Follow VideoLAN and distribution vendor security guidance for fixed packages.; Block or quarantine untrusted MKV, WebM, and Matroska attachments where practical..
