Description
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.

Remediation

Vendor Workaround

There is no complete mitigation while processing untrusted MXF content with the affected plugin. If MXF support is not required, disable the MXF plugin in affected GStreamer applications. Otherwise, restrict MXF inputs to trusted sources. Disabling MXF handling prevents legitimate MXF playback and transcoding.
