"The target is running at least one instance of SquirrelMail whose
version number suggests it is affected by one or more cross-site
scripting vulnerabilities :

- Insufficient escaping of integer variables in webmail.php allows a
remote attacker to include HTML / script into a SquirrelMail webpage
(affects 1.4.0-RC1 - 1.4.4-RC1). 

- Insufficient checking of incoming URL vars in webmail.php allows an
attacker to include arbitrary remote web pages in the SquirrelMail
frameset (affects 1.4.0-RC1 - 1.4.4-RC1). 

- A recent change in prefs.php allows an attacker to provide a
specially crafted URL that could include local code into the
SquirrelMail code if and only if PHP's register_globals setting is
enabled (affects 1.4.3-RC1 - 1.4.4-RC1).
