Firefox < 35 Multiple Vulnerabilities

High Nessus Plugin ID 80523


The remote Windows host contains a web browser that is affected by multiple vulnerabilities.


The version of Firefox installed on the remote Windows host is prior to 35.0. 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 where DOM objects with some specific properties can bypass XrayWrappers. This can allow web content to confuse privileged code, potentially enabling privilege escalation. (CVE-2014-8636)

- A flaw exists in the rendering of bitmap images. When rending a malformed bitmap image, memory may not always be properly initialized, which can result in a leakage of data to web content. (CVE-2014-8637)

- 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, which 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)

- A flaw exists in Web Audio that cam allow a small block of memory to be read. (CVE-2014-8640)

- A read-after-free flaw exists in WebRTC due to the way tracks are handled, which can result in a potentially exploitable crash or incorrect WebRTC behavior.

- A flaw exists where delegated Online Certificate Status Protocol responder certificates fail to recognize the id-pkix-ocsp-nocheck extension. This can result in a user connecting to a site with a revoked certificate.

- A flaw exists in the Gecko Media Plugin which can allow an attacker to break out of the sandbox. (CVE-2014-8643)


Upgrade to Firefox 35.0 or later.
