"According to its banner, the version of PHP installed on the remote
host is 5.4.x earlier than 5.4.4, and as such is potentially
affected the following vulnerabilities :

  - An integer overflow error exists in the function
    'phar_parse_tarfile' in the file 'ext/phar/tar.c'. This
    error can lead to a heap-based buffer overflow when
    handling a maliciously crafted TAR files. Arbitrary code
    execution is possible due to this error. (CVE-2012-2386)

  - A weakness exists in the 'crypt' function related to
    the DES implementation that can allow brute-force
    attacks. (CVE-2012-2143)

  - Several design errors involving the incorrect parsing
    of PHP PDO prepared statements could lead to disclosure
    of sensitive information or denial of service.
    (CVE-2012-3450)");
