## Details

Heap-based buffer overflow in the AV1 codec parser when handling certain malformed streams before GStreamer 1.22.9.

## Impact

It is possible for a malicious third party to trigger a crash in the application,
and possibly also effect code execution through heap manipulation.

## Solution

The gst-plugins-bad 1.22.9 releases address the issue.
People using older branches of GStreamer should apply the patch and recompile.
