NVD Description

Note: Versions mentioned in the description apply only to the upstream gstreamer1-plugins-good-qt6-debuginfo package and not the gstreamer1-plugins-good-qt6-debuginfo package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

A flaw was found in GStreamer gst-plugins-good (avidemux). In gst_avi_demux_riff_parse_vprp(), the number of available gst_riff_vprp_video_field_desc entries is calculated by dividing the remaining buffer size by the attacker-controlled vprp->fields value, rather than by sizeof(gst_riff_vprp_video_field_desc). This can cause the parser to treat more field descriptors as available than fit in the input buffer, resulting in out-of-bounds reads. Processing a crafted AVI via playbin/decodebin can crash the application (denial of service). Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072).
