"The remote EulerOS host is missing multiple security updates.");
  script_set_attribute(attribute:"description", value:
"According to the versions of the openssl098e package installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - It was discovered that OpenSSL would accept ephemeral
    RSA keys when using non-export RSA cipher suites. A
    malicious server could make a TLS/SSL client using
    OpenSSL use a weaker key exchange
    method.(CVE-2015-0204)

  - A NULL pointer dereference flaw was found in OpenSSL's
    X.509 certificate handling implementation. A specially
    crafted X.509 certificate could cause an application
    using OpenSSL to crash if the application attempted to
    convert the certificate to a certificate
    request.(CVE-2015-0288)

  - A NULL pointer dereference was found in the way OpenSSL
    handled certain PKCS#7 inputs. An attacker able to make
    an application using OpenSSL verify, decrypt, or parse
    a specially crafted PKCS#7 input could cause that
    application to crash. TLS/SSL clients and servers using
    OpenSSL were not affected by this flaw.(CVE-2015-0289)

  - An integer underflow flaw, leading to a buffer
    overflow, was found in the way OpenSSL decoded
    malformed Base64-encoded inputs. An attacker able to
    make an application using OpenSSL decode a specially
    crafted Base64-encoded input (such as a PEM file) could
    use this flaw to cause the application to crash. Note:
    this flaw is not exploitable via the TLS/SSL protocol
    because the data being transferred is not
    Base64-encoded.(CVE-2015-0292)

  - An out-of-bounds read flaw was found in the
    X509_cmp_time() function of OpenSSL, which is used to
    test the expiry dates of SSL/TLS certificates. An
    attacker could possibly use a specially crafted SSL/TLS
    certificate or CRL (Certificate Revocation List), which
    when parsed by an application would cause that
    application to crash.(CVE-2015-1789)

  - A NULL pointer dereference was found in the way OpenSSL
    handled certain PKCS#7 inputs. An attacker able to make
    an application using OpenSSL verify, decrypt, or parse
    a specially crafted PKCS#7 input could cause that
    application to crash. TLS/SSL clients and servers using
    OpenSSL were not affected by this flaw.(CVE-2015-1790)
