    Simon Kelly discovered a vulnerability in dhcpcd, an RFC2131 and
    RFC1541 compliant DHCP client daemon, that runs with root privileges
    on client machines.  A malicious administrator of the regular or an
    untrusted DHCP server may execute any command with root privileges on
    the DHCP client machine by sending the command enclosed in shell
    metacharacters in one of the options provided by the DHCP server.
    
    This problem has been fixed in version 1.3.17pl2-8.1 for the old
    stable distribution (potato) and in version 1.3.22pl2-2 for the
    testing (sarge) and unstable (sid) distributions.  The current stable
    distribution (woody) does not contain a dhcpcd package.
    
    We recommend that you upgrade your dhcpcd package (on the client
    machine).
    
    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.
