CVE-2016-9397
The jpc_dequantize function in jpc_dec.c in JasPer 1.900.13 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 (3.93%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
