Summary	Integer overflow leading to heap overwrite in RealMedia file handling
Date	2023-07-20 14:00
Affected Versions	GStreamer gst-plugins-ugly 1.x < 1.22.5, 1.x < 1.20.7, 0.10.x

Details

Heap-based buffer overflow in the RealMedia file demuxer when handling malformed files in GStreamer versions before 1.22.5 / 1.20.7.

It is possible for a malicious third party to trigger a crash in the application, and possibly also effect code execution through heap manipulation.

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.
