## Details
|
||
|
|
|
||
|
|
Potential heap overwrite in the mkv demuxer when handling certain Matroska files in GStreamer versions before 1.20.3.
|
||
|
|
|
||
|
|
## Impact
|
||
|
|
|
||
|
|
It is possible for a malicious third party to overwrite data on the heap, and possibly even effect code execution.
|
||
|
|
|
||
|
|
## Solution
|
||
|
|
|
||
|
|
The gst-plugins-good 1.20.3 release addresses the issue. People using older branches of GStreamer should apply the patch and recompile.
