"According to its banner, the version of PHP 5.4.x installed on the
remote host is prior to 5.4.37. It is, therefore, affected by multiple
vulnerabilities:

  - The CGI component has an out-of-bounds read flaw in file
    'cgi_main.c' 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)

  - A use-after-free memory error exists in the function
    'process_nested_data' within 'var_unserializer.re' due
    to the 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 function 'exif_process_unicode' within
    '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.");
