CVE-2016-6881
The zlib_refill function in libavformat/swfdec.c in FFmpeg before 3.1.3 allows remote attackers to cause an infinite loop denial of service via a crafted SWF file.
Does this matter?
Lower severity and a low EPSS score (0.90%). Track it; it rarely justifies an emergency change on its own.
