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.
