Firefox 3.6.x < 3.6.23 Multiple Vulnerabilities

High Nessus Plugin ID 56334


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


The installed version of Firefox 3.6.x is earlier than 3.6.23 and is affected by the following vulnerabilities:

- An integer underflow exists when handling a large JavaScript 'RegExp' expression that can allow a potentially exploitable crash. (CVE-2011-2998)

- If an attacker could trick a user into holding down the 'Enter' key, via a malicious game, for example, a malicious application or extension could be downloaded and executed. (CVE-2011-2372)

- Unspecified errors exist that can be exploited to corrupt memory. No additional information is available at this time. (CVE-2011-2995, CVE-2011-2996)

- There is an error in the implementation of the 'window.location' JavaScript object when creating named frames. This can be exploited to bypass the same-origin policy and potentially conduct cross-site scripting attacks. (CVE-2011-2999)

- A weakness exists when handling the 'Location' header. This can lead to response splitting attacks when visiting a vulnerable web server. The same fix has been applied to the headers 'Content-Length' and 'Content-Disposition'. (CVE-2011-3000)


Upgrade to Firefox 3.6.23 or later.
