"According to its banner, the version of PHP installed on the remote
host is older than 5.2.3. It is, therefore, affected by multiple
vulnerabilities:

  - A buffer overflow in the sqlite_decode_function() in
    the bundled sqlite library could allow context-dependent
    attackers to execute arbitrary code. (CVE-2007-1887)

  - A CRLF injection vulnerability in the
    FILTER_VALIDATE_EMAIL filter could allow an attacker to
    inject arbitrary email headers via a special email
    address. This only affects Mandriva Linux 2007.1.
    (CVE-2007-1900)

  - An infinite-loop flaw was discovered in the PHP gd
    extension. A script that could be forced to process PNG
    images from an untrusted source could allow a remote
    attacker to cause a denial of service. (CVE-2007-2756)

  - An integer overflow flaw was found in the
    chunk_split() function that ould possibly execute
    arbitrary code as the apache user if a remote attacker
    was able to pass arbitrary data to the third argument of
    chunk_split() (CVE-2007-2872).

  - An open_basedir and safe_mode restriction bypass which 
    could allow context-dependent attackers to determine the
    existence of arbitrary files. (CVE-2007-3007)");
