## Details

Heap-based buffer overflow in the AV1 codec parser when handling certain malformed streams before GStreamer 1.22.7

## 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 1.22.7 releases address the issue. People using older branches of GStreamer should apply the patch and recompile.
