    We have become aware that the version mailman as supplied in Debian GNU/Linux 2.1 has a problem with verifying list administrators. The problem is that the cookie value generation used was predictable, so using forged authentication cookies it was possible to access the list administration webpages without knowing the proper password.

    We have become aware that the version mailman as supplied in Debian
    GNU/Linux 2.1 has a problem with verifying list administrators. The
    problem is that the cookie value generation used was predictable, so
    using forged authentication cookies it was possible to access the
    list administration webpages without knowing the proper password.
    More information about this vulnerability can be found at
    http://www.python.org/pipermail/mailman-developers/1999-
    June/001128.html
    
    This has been fixed in version 1.0rc2-5.
    
    We recommend you upgrade your mailman package immediately.
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
