Mozilla Firefox 3.6 < 3.6.23 Multiple Vulnerabilities

High

Synopsis

The remote host has a web browser installed that is vulnerable to multiple attack vectors.

Description

The remote host has a web browser installed that is vulnerable to multiple attack vectors.

Versions of Firefox 3.6 earlier than 3.6.23 are potentially affected by the following security issues : - An integer underflow exists when handling a large JavaScript 'RegExp' expression that can allow a potentially exploitable crash. (Issue 684815) - 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 error 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)

Solution

Upgrade to Firefox 3.6.23 or later.
