Security Advisory 2021-0002 (CVE-2021-3497)
Summary Use-after-free in matroska demuxing
Date 2021-03-15 16:00
Affected Versions GStreamer gst-plugins-good 1.x <= 1.18.3, 0.10.x > 0.10.8
IDs GStreamer-SA-2021-0002
CVE-2021-3497

Details

GStreamer before 1.18.4 might access already-freed memory in error code paths when demuxing certain malformed Matroska files.

Impact

It might be possible for a malicious third party to trigger a crash in the application, but possibly also an arbitrary code execution with the privileges of the target user.

Solution

The gst-plugins-good 1.18.4 release addresses the issue. People using older branches of GStreamer should apply the patch and recompile.
