Security Advisory 2026-0011 (CVE-2026-3084, ZDI-CAN-28910)
| Summary | Out-of-bounds write in H.266 video parser when parsing picture partitions |
| Date | 2026-02-25 |
| Affected Versions | GStreamer gst-plugins-bad >= 1.25.1, < 1.28.1 |
| IDs | GStreamer-SA-2026-0011 CVE-2026-3084 ZDI-CAN-28910 |
Details
An out-of-bound write in the H.266 video bitstream parser when parsing picture partitions can cause crashes for certain input files, and could possibly also allow code execution through heap manipulation.
Impact
It is possible for a malicious third party to trigger a buffer overflow that can result in a crash of the application and possibly also allow code execution through stack manipulation.
Solution
The gst-plugins-bad 1.28.1 release addresses the issue. People using older versions of GStreamer should apply the patch and recompile.
