## 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.
