In libavformat/mxfdec.c in FFmpeg 3.3.3 -> 2.4, a DoS in mxf_read_index_entry_array() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted MXF file, which claims a large "nb_index_entries" field in the header but does not contain sufficient backing data, is provided, the loop would consume huge CPU resources, since there is no EOF check inside the loop. Moreover, this big loop can be invoked multiple times if there is more than one applicable data segment in the crafted MXF file.

Security readout for executives and security teams

This issue can let a malicious MXF media file make vulnerable FFmpeg processing consume excessive CPU. The business risk is service disruption where FFmpeg or libavformat handles untrusted media uploads, transcoding jobs, or automated file inspection. Exposure is most likely in systems using affected FFmpeg versions described as 2.4 through 3.3.3, especially services that parse or transcode MXF files from external users or partners. Prioritize patching internet-facing or customer-facing media ingestion services. Internal-only batch processors are lower urgency but still need remediation because crafted files can cause resource exhaustion. Mitigation focus: Upgrade FFmpeg or distribution packages to versions containing the referenced fixes.; Apply Debian security updates if using affected Debian libav packages.; Limit or quarantine untrusted MXF file ingestion until patched..
