CVE-2016-3623
The rgb2ycbcr tool in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (divide-by-zero) by setting the (1) v or (2) h parameter to 0.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.54%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
