Security Advisory 2023-0004 (ZDI-CAN-21443)
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
IDs GStreamer-SA-2023-0004
ZDI-CAN-21443

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.
