+  <synopsis>
+    SquirrelMail fails to properly sanitize user input, which could lead to
+    arbitrary code execution and compromise webmail accounts.

+    <p>
+    SquirrelMail is a webmail package written in PHP. It supports IMAP
+    and SMTP and can optionally be installed with SQL support.

+    SquirrelMail fails to properly sanitize certain strings when
+    decoding specially-crafted strings, which can lead to PHP file
+    inclusion and XSS.
+    </p>
+    <ul>
+    <li>Insufficient checking of incoming URLs
+    in prefs.php (CAN-2005-0075) and in webmail.php (CAN-2005-0103).</li>
+    <li>Insufficient escaping of integers in webmail.php
+    (CAN-2005-0104).</li>
+    </ul>
+  </description>
+  <impact type="high">
+    <p>
+    By sending a specially-crafted URL, an attacker can execute
+    arbitrary code from the local system with the permissions of the web
+    server. Furthermore by enticing a user to load a specially-crafted URL,
+    it is possible to display arbitrary remote web pages in Squirrelmail's
+    frameset and execute arbitrary scripts running in the context of the
+    victim's browser. This could lead to a compromise of the user's webmail
+    account, cookie theft, etc.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    The arbitrary code execution is only possible with
+    "register_globals" set to "On". Gentoo ships PHP with
+    "register_globals" set to "Off" by default. There are no known
+    workarounds for the other issues at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All SquirrelMail users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=mail-client/squirrelmail-1.4.4"</code>
+    <p>
+    Note: Users with the vhosts USE flag set should manually use
+    webapp-config to finalize the update.
+    </p>
