Security Advisory 2023-0003 (ZDI-CAN-20994, CVE-2023-37329)
Summary Heap overwrite in PGS subtitle overlay decoder
Date 2023-06-20 18:00
Affected Versions GStreamer gst-plugins-bad 1.x < 1.22.4, 1.x < 1.20.7, 0.10.x
IDs GStreamer-SA-2023-0003
ZDI-CAN-20994
CVE-2023-37329

Details

Heap-based buffer overflow in the PGS blu-ray subtitle decoder when handling certain files in GStreamer versions before 1.22.4 / 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-bad 1.22.4 / 1.20.7 releases address the issue. People using older branches of GStreamer should apply the patch and recompile.
