Synopsis: The remote web server uses a version of PHP that is affected by
multiple vulnerabilities.

Description
According to its banner, the version of PHP 5.3.x installed on the
remote host is older than 5.3.6.

  - A NULL pointer can be dereferenced in the function
    '_zip_name_locate()' when processing empty archives and
    can lead to application crashes or code execution.
    Exploitation requires the 'ZIPARCHIVE::FL_UNCHANGED'
    setting to be in use. (CVE-2011-0421)

  - A variable casting error exists in the Exif extention
    which can allow denial of service attacks when handling
    crafted 'Image File Directory' (IFD) header values in
    the PHP function 'exif_read_data()'. Exploitation
    requires a 64bit system and a config setting
    'memory_limit' above 4GB or unlimited. (CVE-2011-0708)

  - An integer overflow vulnerability exists in the
    implementation of the PHP function 'shmop_read()' and
    can allow arbitrary code execution. (CVE-2011-1092)

  - Errors exist in the file 'phar/phar_object.c' in which
    calls to 'zend_throw_exception_ex()' pass data as a
    string format parameter. This can lead to memory
    corruption when handling PHP archives (phar).
    (CVE-2011-1153)

  - A buffer overflow error exists in the C function
    'xbuf_format_converter' when the PHP configuration value
    for 'precision' is set to a large value and can lead to
    application crashes. (CVE-2011-1464)

  - An integer overflow error exists in the C function
    'SdnToJulian()' in the Calendar extension and can lead
    to application crashes. (CVE-2011-1466)

  - An unspecified error exists in the implementation of
    the PHP function 'numfmt_set_symbol()' and PHP method
    'NumberFormatter::setSymbol()' in the Intl extension.
    This error can lead to application crashes.
    (CVE-2011-1467)

  - Multiple memory leaks exist in the OpenSSL extension
    in the PHP functions 'openssl_encrypt' and
    'openssl_decrypt'. (CVE-2011-1468)

  - An unspecified error exists in the Streams component
    when accessing FTP URLs with an HTTP proxy.
    (CVE-2011-1469)

  - An integer signedness error and an unspecified error
    exist in the Zip extension and can lead to denial of
    service via certain ziparchive streams. (CVE-2011-1470,
    CVE-2011-1471)

  - An unspecified error exists in the security enforcement
    regarding the parsing of the fastcgi protocol with the
    'FastCGI Process Manager' (FPM) SAPI.

Solution
Upgrade to PHP 5.3.6 or later.
