gstreamer1-plugins-good: gstreamer: unsigned integer underflow in avidemux FUJIFILM strd parsing leading to out-of-bounds read/write

A flaw was found in GStreamer gst-plugins-good avidemux. When parsing FUJIFILM metadata in an AVI strd chunk, gstavidemuxparsestrd decrements a remaining-length counter by fixed offsets 98 and 10 bytes without verifying sufficient data remains. For crafted strd payloads of exactly 106 or 107 byte...
