    It was discovered that LibTIFF incorrectly handled certain files. If a user were tricked into opening a
    specially crafted file, an attacker could possibly use this issue to cause the application to crash,
    resulting in a denial of service. (CVE-2023-52356)

    It was discovered that LibTIFF incorrectly handled certain image files with the tiffcp utility. If a user
    were tricked into opening a specially crafted image file, an attacker could possibly use this issue to
    cause tiffcp to crash, resulting in a denial of service. (CVE-2023-6228)

    It was discovered that LibTIFF incorrectly handled certain files. If a user were tricked into opening a
