"Details

Heap-based buffer overflow in the EXIF image tag parser when handling certain malformed streams before GStreamer 1.24.3 or 1.22.12.
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-base 1.24.3 and 1.22.12 releases address the issue. People using older branches of GStreamer should apply the patch and recompile."
