  script_set_attribute(attribute:"synopsis", value:
"A web application on the remote host is affected by multiple
vulnerabilities.");
  script_set_attribute(attribute:"description", value:
"According to its self-reported version number, the Puppet Enterprise
application running on the remote host is 3.x prior to 3.8.1. It is,
therefore, affected by the following vulnerabilities :

  - An XML external entity injection (XXE) flaw exists in
    the Apache ActiveMQ component due to a faulty
    configuration that allows an XML parser to accept XML
    external entities from untrusted sources. A remote
    attacker, by sending crafted XML data, can exploit this
    to disclose arbitrary files. (CVE-2014-3600)

  - An authentication bypass vulnerability exists in the
    Apache ActiveMQ component due to a flaw in the
    LDAPLoginModule implementation. A remote attacker can
    exploit this to bypass authentication mechanisms.
    (CVE-2014-3612)

  - Multiple cross-site scripting vulnerabilities exist in
    the administrative console of Apache ActiveMQ that allow
    a remote attacker to inject arbitrary HTML or web
    scripts. (CVE-2014-8110)

  - An invalid free memory error exists due to improper
    validation of user-supplied input when a DTLS peer
    receives application data between ChangeCipherSpec and
    Finished messages. A remote attacker can exploit this to
    corrupt memory, resulting in a denial of service or
    the execution of arbitrary code. (CVE-2014-8176)

  - A denial of service vulnerability exists when processing
    an ECParameters structure due to an infinite loop that
    occurs when a specified curve is over a malformed binary
    polynomial field. A remote attacker can exploit this to
    perform a denial of service against any system that
    processes public keys, certificate requests, or
    certificates. This includes TLS clients and TLS servers
    with client authentication enabled. (CVE-2015-1788)

  - A denial of service vulnerability exists due to improper
    validation of the content and length of the ASN1_TIME
    string by the X509_cmp_time() function. A remote
    attacker can exploit this, via a malformed certificate
    and CRLs of various sizes, to cause a segmentation
    fault, resulting in a denial of service condition. TLS
    clients that verify CRLs are affected. TLS clients and
    servers with client authentication enabled may be
    affected if they use custom verification callbacks.
    (CVE-2015-1789)

  - A NULL pointer dereference flaw exists in the PKCS#7
    parsing code due to incorrect handling of missing inner
    'EncryptedContent'. This allows a remote attacker, via
    specially crafted ASN.1-encoded PKCS#7 blobs with
    missing content, to cause a denial of service condition
    or other potential unspecified impacts. (CVE-2015-1790)

  - A double-free error exists due to a race condition that
    occurs when a NewSessionTicket is received by a
    multi-threaded client when attempting to reuse a
    previous ticket. (CVE-2015-1791)

  - A denial of service vulnerability exists in the CMS code
    due to an infinite loop that occurs when verifying a
    signedData message. A remote attacker can exploit this
    to cause a denial of service condition. (CVE-2015-1792)

  - A double-free memory flaw exists in PostgreSQL due to
    a timeout interrupt occurring partway in the session
    shutdown sequence. A remote attacker, by closing
    an SSL session when the authentication timeout expires,
    can exploit this flaw to cause a denial of service.
    (CVE-2015-3165)

  - An out-of-memory condition exists in the printf()
    functions in PostgreSQL due to a failure to check for
    errors. A remote attacker can exploit this to access
    sensitive information. (CVE-2015-3166)

  - A flaw exists in contrib/pgcrypto in PostgreSQL due
    to cases of decryption reporting other error message
    texts, which a remote attacker can use to recover
    keys from other systems. (CVE-2015-3167)

  - A man-in-the-middle vulnerability, known as Logjam,
    exists due to a flaw in the SSL/TLS protocol. A remote
    attacker can exploit this flaw to downgrade connections
    using ephemeral Diffie-Hellman key exchange to 512-bit
    export-grade cryptography. (CVE-2015-4000)");
