CVE-2016-8331
Status: ModifiedHigh (8.1)—
An exploitable remote code execution vulnerability exists in the handling of TIFF images in LibTIFF version 4.0.6. A crafted TIFF document can lead to a type confusion vulnerability resulting in remote code execution. This vulnerability can be triggered via a TIFF file delivered to the application using LibTIFF's tag extension functionality.
