Upstream source description

A flaw was found in GStreamer gst-plugins-good (avidemux). In the superindex and subindex parsers, integer overflow can bypass bounds checks and cause out-of-bounds reads. Because avidemux is auto-plugged by playbin, decodebin, and gst-discoverer, opening or previewing a crafted AVI is sufficient to trigger the issue. Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072).
