CVE-2017-7601
LibTIFF 4.0.7 has a "shift exponent too large for 64-bit type long" undefined behavior issue, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
