"The remote Cisco ASA device is running a software version known to be
affected by multiple OpenSSL related vulnerabilities :

  - A buffer overflow error exists related to invalid DTLS
    fragment handling that could lead to execution of
    arbitrary code. Note this issue only affects OpenSSL
    when used as a DTLS client or server. (CVE-2014-0195)

  - An unspecified error exists that could allow an
    attacker to cause usage of weak keying material
    leading to simplified man-in-the-middle attacks.
    (CVE-2014-0224)

Note that Nessus has not checked for the presence of workarounds that
may mitigate these vulnerabilities.");
