A flaw was found in the GStreamer gst-plugins-bad MXF plugin. Insufficient bounds checks when parsing crafted VANC data can cause an out-of-bounds read in the demuxer, while an incorrect buffer size calculation when muxing multiple ancillary packets can cause an out-of-bounds write. Processing affected content may crash the application, resulting in a denial of service.
