SquirrelMail Cross Site Scripting in Encoded Text
------------------------------------------------------------------------
SUMMARY
<http://www.squirrelmail.org> SquirrelMail is "a standards-based webmail
package written in PHP4. It includes built-in pure PHP support for the
IMAP and SMTP protocols, and all pages render in pure HTML 4.0 (with no
JavaScript required) for maximum compatibility across browsers. It has
very few requirements and is very easy to configure and install.
SquirrelMail has all the functionality you would want from an email
client, including strong MIME support, address books, and folder
manipulation".
There is a cross site scripting issue in SqurrielMail's decoding of
encoded text in certain headers. SquirrelMail correctly decodes the
specially crafted header, but doesn't sanitize the decoded strings.
