| Date | 2023-07-20 14:00 |

Details
Heap-based buffer overflow in the RealMedia file demuxer when handling malformed files in GStreamer versions before 1.22.5 / 1.20.7.
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-ugly 1.22.5 / 1.20.7 releases address the issue. People using older branches of GStreamer should apply the patch and recompile.
