remote host is a version prior to 5.5.3.  It is, therefore,
potentially affected by the following vulnerabilities : 

  - An error exists related to the 'Sessions' subsystem
    that can allow an attacker to hijack the session of
    another user. (CVE-2011-4718 / Bug #60491)

  - An error exists related to certificate validation, the
    'subjectAltName' field and certificates containing NULL
    bytes. This error can allow spoofing attacks.
    (CVE-2013-4248)

Note that this plugin does not attempt to exploit these
vulnerabilities, but instead relies only on PHP's self-reported
version number.");
