CVE-2016-9448
The TIFFFetchNormalTag function in LibTiff 4.0.6 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) by setting the tags TIFF_SETGET_C16ASCII or TIFF_SETGET_C32_ASCII to values that access 0-byte arrays.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.98%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
