Mozilla Thunderbird < 31.6 Multiple Vulnerabilities (Mac OS X)

High Nessus Plugin ID 82501


The remote Mac OS X host contains a mail client that is affected by multiple vulnerabilities.


The version of Thunderbird installed on the remote Mac OS X host is prior to 31.6. It is, therefore, affected by the following vulnerabilities :

- A privilege escalation vulnerability exists which relates to anchor navigation. A remote attacker can exploit this to bypass same-origin policy protections, allowing a possible execution of arbitrary scripts in a privileged context. (CVE-2015-0801)

- Access to certain privileged internal methods is retained when navigating from windows created to contain privileged UI content to unprivileged pages. An attacker can exploit this to execute arbitrary JavaScript with elevated privileges. (CVE-2015-0802)

- A cross-site request forgery (XSRF) vulnerability exists in the sendBeacon() function due to cross-origin resource sharing (CORS) requests following 30x redirections. (CVE-2015-0807)

- Multiple memory safety issues exist within the browser engine. A remote attacker can exploit these to corrupt memory and possibly execute arbitrary code.

- A privilege escalation vulnerability exists related to documents loaded through a 'resource:' URL. An attacker can exploit this to load pages and execute JavaScript with elevated privileges. (CVE-2015-0816)


Upgrade to Thunderbird 31.6 or later.
