CVE-2006-3463

Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.78%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The EstimateStripByteCounts function in TIFF library (libtiff) before 3.8.2 uses a 16-bit unsigned short when iterating over an unsigned 32-bit value, which allows context-dependent attackers to cause a denial of service via a large td_nstrips value, which triggers an infinite loop.
