CVE-2017-14223 (opens in a new tab)How to fix?
Upgrade Alpine:3.12 ffmpeg to version 3.3.4-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ffmpeg package and not the ffmpeg package as distributed by Alpine.
See How to fix? for Alpine:3.12 relevant fixed versions and status.
In libavformat/asfdec_f.c in FFmpeg 3.3.3, a DoS in asf_build_simple_index() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted ASF file, which claims a large "ict" field in the header but does not contain sufficient backing data, is provided, the for loop would consume huge CPU and memory resources, since there is no EOF check inside the loop.
