Mozilla Firefox before 35.0 on Windows allows remote attackers to bypass the Gecko Media Plugin (GMP) sandbox protection mechanism by leveraging access to the GMP process, as demonstrated by the OpenH264 plugin's process.

Versions of Mozilla Firefox ESR prior to 31.4 are unpatched for 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 can 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. (CVE-2014-8641)
 - 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. (CVE-2014-8642)
 - A flaw exists in the Gecko Media Plugin which can allow an attacker to break out of the sandbox. (CVE-2014-8643)

  - 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.
    (CVE-2014-8641)

  - 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.
    (CVE-2014-8642)

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