"According to its self-reported version number and configuration, the
remote Juniper Junos device is affected by multiple vulnerabilities in
the included PHP version :

  - An unspecified flaw exists in the SQLite extension
    that allows an unauthenticated, remote attacker to
    bypass the 'open_basedir' constraint. (CVE-2012-3365)

  - A heap-based buffer overflow condition exists in file
    ext/xml/xml.c due to not properly considering parsing
    depth. An unauthenticated, remote attacker can exploit
    this issue, via a specially crafted XML document that is
    processed by the xml_parse_into_struct() function, to
    cause a denial of service condition or the execution of
    arbitrary code. (CVE-2013-4113)

  - A memory corruption issue exists in the PHP OpenSSL
    extension in the openssl_x509_parse() function due to
    improper sanitization of user-supplied input when
    parsing 'notBefore' and 'notAfter' timestamps in X.509
    certificates. An unauthenticated, remote attacker can
    exploit this issue, via a specially crafted certificate,
    to cause a denial of service condition or the execution
    of arbitrary code. (CVE-2013-6420)

  - A double-free error exists in the
    zend_ts_hash_graceful_destroy() function within file
    Zend/zend_ts_hash.c that allows an unauthenticated,
    remote attacker to cause a denial of service condition.
    (CVE-2014-9425)");
