CVE-2022-1921

Heap overwrite via wrapped DIB buffer dimensions

Published Jul 19, 2022 · Updated Aug 3, 2024

Integer overflow in GStreamer Good Plug-ins before 1.20.3 allows attackers to overwrite heap memory by supplying a crafted AVI file. gst_avi_demux_invert calculates DIB row stride and image size in narrow integer arithmetic, so wrapped values pass its buffer-length check before in-place row swapping. A GStreamer-based application must parse the crafted file; the resulting corruption allows an application crash and provides a path to code execution.
