Linux-Mandrake Security Update Advisory
________________________________________________________________________
Package name: dhcp
Date: July 21th, 2000
Advisory ID: MDKSA-2000:022
Affected versions: 7.0, 7.1
________________________________________________________________________
Problem Description:
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.
________________________________________________________________________
Please verify these md5 checksums of the updates prior to upgrading to
ensure the integrity of the downloaded package. You can do this by
running the md5sum program on the downloaded package by using
"md5sum package.rpm".

To upgrade automatically, use « MandrakeUpdate ».
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:
http://www.linux-mandrake.com/en/ftp.php3.
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.
Please be aware that sometimes it takes the mirrors a few hours to
update, so if you want an immediate upgrade, please use one of the two
above-listed mirrors.
