Synopsis :

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

Description :

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)
