A stack-based buffer overflow was found in the GStreamer Plugins Bad when handling malformed files with H.265 video streams.

Description Patrick Del Bello 2023-12-14 17:46:55 UTC 
Stack-based buffer overflow in the H.265 video parser when handling malformed H.265 video streams in GStreamer versions before 1.22.6
It is possible for a malicious third party to trigger a crash in the application, and possibly also effect code execution through stack manipulation.
