SynopsisThe remote host has an email client installed that is vulnerable to multiple attack vectors.
DescriptionVersions of Mozilla Thunderbird prior to 31.4 are prone to 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)
SolutionUpgrade to Thunderbird 31.4, or later.
