## Details

Potential heap overwrite in the mkv demuxer when handling certain Matroska/WebM files in GStreamer versions before 1.20.3.

## Impact

It is possible for a malicious third party to trigger a crash in the application, and possibly also overwrite data on the heap.

## Solution

The gst-plugins-good 1.20.3 release addresses the issue. People using older branches of GStreamer should apply the patch and recompile.
