Multiple vulnerabilities have been discovered in the libtiff library and

CVE-2017-11613

    Ddenial of service vulnerability in the TIFFOpen function. A crafted

    There is an uncontrolled resource consumption in TIFFSetDirectory function
    of src/libtiff/tif_dir.c, which can cause denial of service through a
