High impact if exploited, but EPSS currently rates exploitation as unlikely (7.39%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The mget function in softmagic.c in file 5.x, as used in the Fileinfo component in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8, does not properly maintain a certain pointer relationship, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted string that is mishandled by a "Python script text executable" rule.
