In libavformat/nsvdec.c in FFmpeg 2.4 and 3.3.3, a DoS in nsv_parse_NSVf_header() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted NSV file, which claims a large "table_entries_used" field in the header but does not contain sufficient backing data, is provided, the loop over 'table_entries_used' would consume huge CPU resources, since there is no EOF check inside the loop.

Security readout for executives and security teams

This flaw can make affected FFmpeg versions spend excessive CPU while parsing a specially crafted NSV media file. The main business risk is service slowdown or denial of service in systems that accept or process untrusted media. Exposure is most likely in applications, batch media pipelines, or user-facing upload services using affected FFmpeg 2.4 or 3.3.3 code to parse untrusted NSV files. Prioritize remediation where FFmpeg processes files from customers, partners, or the internet. Internal-only media tooling can be scheduled normally after inventory confirms limited exposure. Mitigation focus: Upgrade FFmpeg/libav packages using vendor security guidance.; Ensure fixes include the referenced FFmpeg EOF-check commit.; Apply Debian DSA-3996 or DLA 1630-1 packages where applicable..
