high Nessus Plugin ID 55418


The remote Mac OS X host contains a web browser that is affected by multiple vulnerabilities.


The installed version of Firefox is 3.6.x earlier than 3.6.18. Such versions are potentially affected by the following security issues :

- Multiple memory safety issues can lead to application crashes and possibly remote code execution.
(CVE-2011-2374, CVE-2011-2376, CVE-2011-2364, CVE-2011-2365)

- A use-after-free issue when viewing XUL documents with scripts disabled could lead to code execution.

- A memory corruption issue due to multipart / x-mixed-replace images could lead to memory corruption.

- When a JavaScript Array object has its length set to an extremely large value, the iteration of array elements that occurs when its reduceRight method is called could result in code execution due to an invalid index value being used. (CVE-2011-2371)

- Multiple dangling pointer vulnerabilities could lead to code execution. (CVE-2011-0083, CVE-2011-2363, CVE-2011-0085)

- An error in the way cookies are handled could lead to information disclosure. (CVE-2011-2362)


Upgrade to Firefox 3.6.18 or later.
