CVE-2017-14169 (opens in a new tab)How to fix?
Upgrade Debian:10 ffmpeg to version 7:3.3.4-1 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 Debian.
See How to fix? for Debian:10 relevant fixed versions and status.
In the mxf_read_primer_pack function in libavformat/mxfdec.c in FFmpeg 3.3.3 -> 2.4, an integer signedness error might occur when a crafted file, which claims a large "item_num" field such as 0xffffffff, is provided. As a result, the variable "item_num" turns negative, bypassing the check for a large value.
