"According to its banner, the version of PHP 5.6.x installed on the
remote host is prior to 5.6.5. It is, therefore, affected by multiple
vulnerabilities:

  - A double free vulnerability in the
    zend_ts_hash_graceful_destroy function in
    zend_ts_hash.c in the Zend Engine could allow a remote
    attacker to cause a denial of service. (CVE-2014-9425)

  - An out-of-bounds read flaw in file 'cgi_main.c' exists
    when nmap is used to process an invalid file that begins
    with a hash character (#) but lacks a newline character.
    A remote attacker, using a specially crafted PHP file,
    can exploit this vulnerability to disclose memory
    contents, cause a denial of service, or possibly execute
    code. (CVE-2014-9427)

  - The mconvert function in softmagic.c does not properly
    handle a certain string-length field during a copy of a
    truncated version of a Pascal string, which could allow
    a remote attacker to cause a denial of service.
    (CVE-2014-9652)

  - An out-of-bounds read issue exists in the GetCode_()
    function in 'gd_gif_in.c'. This allows a remote attacker
    to disclose memory contents. (CVE-2014-9709)

  - A use-after-free memory error exists in the
    process_nested_data() function in 'var_unserializer.re'
    due to improper handling of duplicate numerical keys
    within the serialized properties of an object. A remote
    attacker, using a crafted unserialize method call, can
    exploit this vulnerability to execute arbitrary code.
    (CVE-2015-0231)

  - A flaw exists in the exif_process_unicode() function in
    'exif.c' that allows freeing an uninitialized pointer. A
    remote attacker, using specially crafted EXIF data in a
    JPEG image, can exploit this to cause a denial of
    service or to execute arbitrary code. (CVE-2015-0232)

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