## Details
|
||
|
|
|
||
|
|
Stack-based buffer overflow in the H.265 video parser when handling malformed H.265 video streams in GStreamer versions before 1.22.6
|
||
|
|
|
||
|
|
## Impact
|
||
|
|
|
||
|
|
It is possible for a malicious third party to trigger a crash in the application, and possibly also effect code execution through stack manipulation.
|
||
|
|
|
||
|
|
## Solution
|
||
|
|
|
||
|
|
The gst-plugins-bad 1.22.6 releases address the issue. People using older branches of GStreamer should apply the patch and recompile.
