The iptables ip_conntrack_ftp module, which is used for stateful inspection of FTP traffic, does not validate parameters passed to it in an FTP PORT command. Due to this flaw, carefully constructed PORT commands could open arbitrary holes in the firewall. This hole has been fixed, as well as a number of other bugs for the 2.4 kernel shipped with Mandrake Linux 8.0 NOTE: This update is *not* meant to be done via MandrakeUpdate! You must download the necessary RPMs and upgrade manually by following these steps: 1. Type: rpm -ivh kernel-2.4.7-12.3mdk.i586.rpm 2. Type: mv kernel-2.4.7-12.3mdk.i586.rpm /tmp 3. Type: rpm -Fvh *.rpm 4. You may wish to edit /etc/lilo.conf to ensure a new entry is in place. The new kernel will be the last entry. Change any options you need to change. 5. Type: /sbin/lilo -v You may then reboot and use the nwe kernel and remove the older kernel when you are comfortable using the upgraded one. ________________________________________________________________________ References: http://www.tempest.com.br/advisories/01-2001.html ________________________________________________________________________ Please verify the update prior to upgrading to ensure the integrity of the downloaded package. You can do this with the command: rpm --checksig package.rpm You can get the GPG public key of the Mandrake Linux Security Team at http://www.linux-mandrake.com/en/security/RPM-GPG-KEYS If you use MandrakeUpdate, the verification of md5 checksum and GPG signature is performed automatically for you.

You can download the updates directly from one of the mirror sites 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 Mandrake Linux 8.0, look for it in "updates/8.0/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.
