    The proftpd version that was distributed in Debian GNU/Linux 2.1 had several buffer overruns that could be exploited by remote attackers. A short list of problems: * user input was used in snprintf() without sufficient checks * there was an overflow in the log_xfer() routine * you could overflow a buffer by using very long pathnames

    The proftpd version that was distributed in Debian GNU/Linux 2.1
    had several buffer overruns that could be exploited by remote
    attackers. A short list of problems:
    * user input was used in snprintf() without sufficient checks
    * there was an overflow in the log_xfer() routine
    * you could overflow a buffer by using very long pathnames
    
    Please not that this is not meant to be an exhaustive list.
    
    In addition to the security fixes a couple of Y2K problems were also
    fixed.
    
    We have made a new package with version 1.2.0pre9-4 to address these
    issues, and we recommend to upgrade your proftpd package immediately.
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
