Mandrake Linux Security Advisory : kernel (MDKSA-2001:071)

high Nessus Plugin ID 13886

Synopsis

The remote Mandrake Linux host is missing one or more security updates.

Description

A security hole was found in the earlier Linux 2.4 kernels dealing with iptables RELATED connection tracking. 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.

Solution

Update the affected packages.
