CVE-2017-7592
The putagreytile function in tif_getimage.c in LibTIFF 4.0.7 has a left-shift 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 (1.95%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
