CVE-2017-14171

MEDIUM

FFmpeg 2.4 and 3.3.3 - Denial of Service via NSV Header Parsing

Title source: llm
STIX 2.1

Description

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.
