gstreamer1-plugins-good: gst-plugins-good: unbounded memory growth in rtph264depay and rtph265depay RTP depayloaders
A flaw was found in the GStreamer gst-plugins-good package. The rtph264depay and rtph265depay RTP depayloader elements do not enforce a maximum size limit on the reassembly buffer used during fragmented RTP packet processing. A remote, unauthenticated attacker can send a continuous stream of RTP...
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...
