Description
A vulnerability in GStreamer's gst-plugins-good (avidemux) component allows out-of-bounds reads due to improper pointer dereferencing in the Nikon metadata tag parser. This flaw can be triggered by opening or previewing a crafted AVI file, as avidemux is auto-plugged by common GStreamer elements. The issue can cause application crashes or limited information disclosure. It was fixed in gst-plugins-good version 1.28.6.
