"The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2023:4736-1 advisory.

  - LibTIFF master branch has an out-of-bounds read in LZWDecode in libtiff/tif_lzw.c:619, 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 b4e79bfa. (CVE-2022-1622)

  - An issue was discovered in function TIFFReadDirectory libtiff before 4.4.0 allows attackers to cause a
    denial of service via crafted TIFF file. (CVE-2022-40090)

  - A flaw was found in tiffcrop, a program distributed by the libtiff package. A specially crafted tiff file
    can lead to an out-of-bounds read in the extractImageSection function in tools/tiffcrop.c, resulting in a
    denial of service and limited information disclosure. This issue affects libtiff versions 4.x.
    (CVE-2023-1916)

  - loadImage() in tools/tiffcrop.c in LibTIFF through 4.5.0 has a heap-based use after free via a crafted
    TIFF image. (CVE-2023-26965)

  - A NULL pointer dereference flaw was found in Libtiff's LZWDecode() function in the libtiff/tif_lzw.c file.
    This flaw allows a local attacker to craft specific input data that can cause the program to dereference a
    NULL pointer when decompressing a TIFF format file, resulting in a program crash or denial of service.
    (CVE-2023-2731)

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