"According to its banner, the version of PHP running on the remote web
server is 5.5.x prior to 5.5.35. It is, therefore, affected by
multiple vulnerabilities :

  - A signedness error exists in the GD Graphics library
    within file gd_gd2.c due to improper validation of
    user-supplied input when handling compressed GD2 data.
    An unauthenticated, remote attacker can exploit this to
    cause a heap-based buffer overflow, resulting in a
    denial of service condition or the execution of
    arbitrary code. (CVE-2016-3074)

  - An out-of-bounds read error exists within file
    ext/intl/grapheme/grapheme_string.c when handling
    negative offsets in the zif_grapheme_stripos() function.
    An unauthenticated, remote attacker can exploit this to
    cause a denial of service condition or disclose memory
    contents.

  - An out-of-bounds read error exists in the php_str2num()
    function within file ext/bcmath/bcmath.c when handling
    negative scales. An unauthenticated, remote attacker can
    exploit this to cause a denial of service condition or
    the disclosure of memory contents.

  - An out-of-bounds read error exists in the
    exif_read_data() function within file ext/exif/exif.c
    when handling exif headers. An unauthenticated, remote
    attacker can exploit this to cause a denial of service
    condition or the disclosure of memory contents.

  - A flaw exists in the xml_parse_into_struct() function
    within file ext/xml/xml.c when handling specially
    crafted XML contents. An unauthenticated, remote
    attacker can exploit this to cause a denial of service
    condition.

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