"According to its banner, the version of PHP installed on the remote
host is older than 5.2.11.  Such versions may be affected by several
security issues :

  - An unspecified error occurs in certificate validation
    inside 'php_openssl_apply_verification_policy'.

  - An unspecified input validation vulnerability affects
    the color index in 'imagecolortransparent()'.

  - An unspecified input validation vulnerability affects
    exif processing.

  - Calling 'popen()' with an invalid mode can cause a
    crash under Windows. (Bug #44683)

  - An integer overflow in 'xml_utf8_decode()' can make it
    easier to bypass cross-site scripting and SQL injection 
    protection mechanisms using a specially crafted string 
    with a long UTF-8 encoding. (Bug #49687)

  - 'proc_open()' can bypass 'safe_mode_protected_env_vars'.
    (Bug #49026)"
