"The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple
vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libtiff: Heap-based buffer over-read in bmp2tiff (CVE-2017-9117)

  - LibTIFF 4.0.3 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a
    crafted TIFF image to the (1) checkInkNamesString function in tif_dir.c in the thumbnail tool, (2)
    compresscontig function in tiff2bw.c in the tiff2bw tool, (3) putcontig8bitCIELab function in
    tif_getimage.c in the tiff2rgba tool, LZWPreDecode function in tif_lzw.c in the (4) tiff2ps or (5)
    tiffdither tool, (6) NeXTDecode function in tif_next.c in the tiffmedian tool, or (7)
    TIFFWriteDirectoryTagLongLong8Array function in tif_dirwrite.c in the tiffset tool. (CVE-2014-8127)

  - LibTIFF prior to 4.0.4, as used in Apple iOS before 8.4 and OS X before 10.10.4 and other products, allows
    remote attackers to cause a denial of service (out-of-bounds write) via a crafted TIFF image.

is installed.");
