Firefox ESR 31.x < 31.4 Multiple Vulnerabilities (Mac OS X)
High Nessus Plugin ID 80519
SynopsisThe remote Mac OS X host contains a web browser that is affected by multiple vulnerabilities.
DescriptionThe version of Firefox ESR 31.x installed on the remote Mac OS X host is prior to 31.4. 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 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 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.
SolutionUpgrade to Firefox ESR 31.4 or later.
