Technical details
An integer overflow in the superindex and subindex parsers of GStreamer's avidemux element allows bounds checks to be bypassed, resulting in out-of-bounds memory reads. The vulnerability is triggered when a user opens or previews a crafted AVI file, as avidemux is auto-plugged by playbin, decodebin, and gst-discoverer. Exploitation results in application crashes (denial of service) or limited memory disclosure, but does not enable arbitrary code execution under default security configurations.
Affected products
- GStreamer gst-plugins-good before 1.28.6
