CVE-2016-9398
The jpc_floorlog2 function in jpc_math.c in JasPer before 1.900.17 allows remote attackers to cause a denial of service (assertion failure) via unspecified vectors.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.98%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
