## Details
|
||
|
|
|
||
|
|
GStreamer before 1.18.4 might cause stack corruptions with streams that have more than 64 audio channels.
|
||
|
|
|
||
|
|
## Impact
|
||
|
|
|
||
|
|
It might be possible for a malicious third party to trigger a crash in the application.
|
||
|
|
|
||
|
|
## Solution
|
||
|
|
|
||
|
|
The gst-libav 1.18.4 release addresses the issue. People using older branches of GStreamer should apply the patch and recompile.
