Mozilla Thunderbird < 31.4 Multiple Vulnerabilities

High

Synopsis

The remote host has an email client installed that is vulnerable to multiple attack vectors.

Description

Versions 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)

Solution

Upgrade to Thunderbird 31.4, or later.
