In FFmpeg 2.4 and 3.3.3, the read_data function in libavformat/hls.c does not restrict reload attempts for an insufficient list, which allows remote attackers to cause a denial of service (infinite loop).

## What to do

- Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory per the references below.
