CVE-2017-14169 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.57% chance of exploitation in the next 30 days.
