|
## Details
|
||
|
|
|
||
|
|
GStreamer before 1.18.4 might access already-freed memory in error code paths when demuxing certain malformed Matroska files.
|
||
|
|
|
||
|
|
## Impact
|
||
|
|
|
||
|
|
It might be possible for a malicious third party to trigger a crash in the application, but possibly also an arbitrary code execution with the privileges of the target user.
|
||
|
|
|
||
|
|
## Solution
|
||
|
|
|
||
|
|
The gst-plugins-good 1.18.4 release addresses the issue. People using older branches of GStreamer should apply the patch and recompile.
