{"id":"CVE-2026-73472","kind":"vulnerability","aliases":["CVE-2026-73472"],"related":[],"title":"GStreamer gst-plugins-good: crafted AVI file triggers out-of-bounds memory read","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).","summary":"An integer overflow in the AVI superindex and subindex parsers of GStreamer's gst-plugins-good lets bounds checks be bypassed and memory be read out of bounds.
