  "statement" : "This vulnerability is rated as moderate because a memory leak in LibTIFF’s TIFFFdOpen function within tif_unix.c could lead to a denial of service, exploitation requires user interaction, as an attacker must persuade a victim to open a specially crafted file. While this does not lead to code execution, repeated exploitation could impact application availability.",
