1. Topic:
The Linux Netfilter team has found a problem in the "IRC connection
tracking" component of the firewall within the linux kernel. This problem
affects Red Hat Linux versions 7.1 and 7.2.
2. Relevant releases/architectures:
Red Hat Linux 7.1 - alpha, athlon, i386, i586, i686, ia64
Red Hat Linux 7.2 - athlon, i386, i586, i686, ia64, s390
3. Problem description:
The Linux Netfilter team has found a problem in the IRC connection
tracking component of the firewall within the linux kernel. This component
is distributed with kernels in Red Hat Linux 7.1 and 7.2, although it is
not used in default installations.
The problem consists of an excessively broad netmask setting which is
applied to check if an "IRC DCC" connection through a masquerading firewall
should be allowed. This results in unwanted ports being opened on the
firewall, which could, depending on the firewall filter ruleset, allow
inbound connections.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0060 to this issue. Thanks to Jozsef Kadlecsik
and Harald Welte of the netfilter team.
Users are advised to upgrade to this errata kernel containing patches
which fix these issues.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied. Red Hat Linux 7.1 users should
update the packages in the XFree86 Erratum (RHEA-2002:010).
The procedure for upgrading the kernel is documented at:
http://www.redhat.com/support/docs/howto/kernel-upgrade/
Please read the directions for your architecture carefully before
proceeding with the kernel upgrade.
Please note that this update is also available via Red Hat Network. Many
people find this to be an easier way to apply updates. To use Red Hat
Network, launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system. Note that you need to select the kernel
explicitly on default configurations of up2date.
Note for customers using Red Hat Linux for the IBM s/390:
Users of Red Hat Linux for the IBM s/390 with binary only kernel modules
(OCO) should contact their vendor to obtain updated modules for this kernel
patch.
