    Zorgon found several buffer overflows in cfsd, a daemon that pushes
    encryption services into the Unix(tm) file system.  We are not yet
    sure if these overflows can successfully be exploited to gain root
    access to the machine running the CFS daemon.  However, since cfsd can
    easily be forced to die, a malicious user can easily perform a denial
    of service attack to it.
    
    This problem has been fixed in version 1.3.3-8.1 for the stable Debian
    distribution and in version 1.4.1-5 for the testing and undtable
    distribution of Debian.
    
    We recommend that you upgrade your cfs package immediately.
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    
    You may use an automated update by adding the resources from the
    footer to the proper configuration.
