Security Advisory 2023-0008 (ZDI-CAN-21768, CVE-2023-40476)
Summary Integer overflow in H.265 video parser leading to stack overwrite
Date 2023-09-20 20:00
Affected Versions GStreamer gst-plugins-bad < 1.22.6
IDs GStreamer-SA-2023-0008
ZDI-CAN-21768
CVE-2023-40476

Details

Stack-based buffer overflow in the H.265 video parser when handling malformed H.265 video streams in GStreamer versions before 1.22.6

Impact

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

Solution

The gst-plugins-bad 1.22.6 releases address the issue. People using older branches of GStreamer should apply the patch and recompile.
