    2024-06-06: CVE-2022-3598 was added to this advisory.

    Multiple heap buffer overflows in tiffcrop.c utility in libtiff library Version 4.4.0 allows attacker to
    trigger unsafe or out of bounds memory access via crafted TIFF image file which could result into
    application crash, potential information disclosure or any other context-dependent impact (CVE-2022-3570)

    LibTIFF 4.4.0 has an out-of-bounds write in extractContigSamplesShifted24bits in tools/tiffcrop.c:3604,
    allowing attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff
    from sources, the fix is available with commit cfbb883b. (CVE-2022-3598)

    processCropSelections in tools/tiffcrop.c in LibTIFF through 4.5.0 has a heap-based buffer overflow (e.g.,
    WRITE of size 307203) via a crafted TIFF image. (CVE-2022-48281)

    A vulnerability was found in libtiff library. This security flaw causes a heap buffer overflow in
    extractContigSamples32bits, tiffcrop.c (CVE-2023-30775)

    Multiple potential integer overflow in tiffcp.c in libtiff <= 4.5.1 can allow remote attackers to cause a
    denial of service (application crash) or possibly execute an arbitrary code via a crafted tiff image which
    triggers a heap-based buffer overflow. (CVE-2023-40745)

    Multiple potential integer overflow in raw2tiff.c in libtiff <= 4.5.1 can allow remote attackers to cause
    a denial of service (application crash) or possibly execute an arbitrary code via a crafted tiff image
    which triggers a heap-based buffer overflow. (CVE-2023-41175)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
