    Helmut Hummel of the typo3 security team discovered that typo3, a web
    content management system, is not properly sanitizing output of the
    exception handler.  This allows an attacker to conduct cross-site
    scripting attacks if either third-party extensions are installed that do
    not sanitize this output on their own or in the presence of extensions
    using the extbase MVC framework which accept objects to controller actions.
    
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 4.3.9+dfsg1-1+squeeze4.
    
    For the testing (wheezy) and unstable (sid) distributions, this problem
    will be fixed soon.
    
    We recommend that you upgrade your typo3-src packages.
