Synopsis :

The remote host is affected by multiple vulnerabilities.

Description :

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

could allow nonce disclosure via the 'FLUSH+RELOAD'
cache side-channel attack. (CVE-2014-0076)

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

- An unspecified error exists related to anonymous ECDH
ciphersuites that could allow denial of service
attacks. Note this issue only affects OpenSSL TLS
