Package : dhcpcd
Vulnerability : remote command execution
Problem-Type : remote
Debian-specific: no
BugTraq Id : 6200

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.
