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 :

- An error exists related to the implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA) that 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.
(CVE-2014-0224)

- An unspecified error exists related to anonymous ECDH ciphersuites that could allow denial of service attacks. Note this issue only affects OpenSSL TLS clients. (CVE-2014-3470)
