The TIFFReadDirectory function in LibTIFF 3.9.0 does not properly validate the data types of codec-specific tags that have an out-of-order position in a TIFF file, which allows remote attackers to cause a denial of service (application crash) via a crafted file, a different vulnerability than CVE-2010-2481.
Improper Input Validation The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly.
