Linux-Mandrake Security Update Advisory dhcp

All versions of the ISC DHCP client program, dhclient, are vulnerable to a root attack by a corrupt DHCP server. This version fixes the vulnerability. Versions of Linux Mandrake prior to 7.0, while including the ISC DHCP server, do not include the DHCP client and are therefore not subject to this vulnerability.

If you want to upgrade manually, download the updated package from one of our FTP server mirrors and uprade with "rpm -Uvh package_name".

You can download the updates directly from: ftp://ftp.linux.tucows.com/pub/distributions/Mandrake/Mandrake/updates ftp://ftp.free.fr/pub/Distributions_Linux/Mandrake/updates

Or try one of the other mirrors listed at:

Updated packages are available in the "updates/[ver]/RPMS/" directory. For example, if you are looking for an updated RPM package for Linux-Mandrake 7.1, look for it in "updates/7.1/RPMS/". Updated source RPMs are available as well, but you generally do not need to download them.
