  vulnerable to XSS attacks. Further, since SquirrelMail displays From headers when listing a folder,
  attacks does not require a user to actually open a message, only view the folder listing.

  For example, a remote attacker could effectively launch a DoS against
  a user by sending a message with a From header such as:

  From:<!--<>(-->John Doe<script>document.cookie='PHPSESSID=xxx<semicolon> path=/'<semicolon></script><>

  which rewrites the session ID cookie and effectively logs the user out.");
