The version of Thunderbird installed on the remote Mac OS X host is prior to 31.4. It is, therefore, affected by the following vulnerabilities :

  - Multiple unspecified memory safety issues exist within     the browser engine. (CVE-2014-8634, CVE-2014-8635)

  - A flaw exists in 'navigator.sendBeacon()' in which it     does not follow the cross-origin resource sharing     specification. This results in requests from     'sendBeacon()' lacking an 'origin' header. This allows     malicious sites to perform XSRF attacks. (CVE-2014-8638)

  - A flaw exists when receiving 407 Proxy Authentication     responses with a 'set-cookie' header. This can allow     a session-fixation attack. (CVE-2014-8639)
