 https://github.com/FFmpeg/FFmpeg/commit/9d00fb9d70ee8c0cc7002b89318c5be00f1bbdad
Description:
 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.
