CVE-2017-14225 (opens in a new tab)How to fix?
Upgrade Ubuntu:16.04 ffmpeg to version 7:2.8.14-0ubuntu0.16.04.1 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 Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
The av_color_primaries_name function in libavutil/pixdesc.c in FFmpeg 3.3.3 may return a NULL pointer depending on a value contained in a file, but callers do not anticipate this, as demonstrated by the avcodec_string function in libavcodec/utils.c, leading to a NULL pointer dereference. (It is also conceivable that there is security relevance for a NULL pointer dereference in av_color_primaries_name calls within the ffprobe command-line program.)
