## Details
|
||
|
|
|
||
|
|
Heap-based buffer overflow in the AV1 codec parser when handling certain malformed streams before GStreamer 1.22.8
|
||
|
|
|
||
|
|
## 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 1.22.8 releases address the issue. People using older branches of GStreamer should apply the patch and recompile.
