CVE-2016-3631
The (1) cpStrips and (2) cpTiles functions in the thumbnail tool in LibTIFF 4.0.6 and earlier allow remote attackers to cause a denial of service (out-of-bounds read) via vectors related to the bytecounts[] array variable.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.90%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
