Red Hat Security Advisory
Synopsis: Updated 2.4 kernel fixes security vulnerabilities and various bugs
Advisory ID: RHSA-2003:172-00
Issue date: 2003-05-14
Updated on: 2003-05-14
Product: Red Hat Linux
Keywords: dos
Cross references: RHSA-2003-098 RHBA-2003-135

CVE Names: CAN-2003-0244 CAN-2003-0246
---------------------------------------------------------------------
1. Topic:
Updated kernel packages that fix a remote denial of service vulnerability
in the TCP/IP stack, and a local privilege vulnerability, are now available.
2. Relevant releases/architectures:
Red Hat Linux 7.1 - athlon, i386, i586, i686
Red Hat Linux 7.2 - athlon, i386, i586, i686
Red Hat Linux 7.3 - athlon, i386, i586, i686
Red Hat Linux 8.0 - athlon, i386, i586, i686
Red Hat Linux 9 - athlon, i386, i586, i686
3. Problem description:
The Linux kernel handles the basic functions of the operating system.
A flaw has been found in several hash table implementations in the kernel
networking code. A remote attacker could send packets with carefully
chosen, forged source addresses in such a way as to make every routing
cache entry get hashed into the same hash chain. The result would be that
the kernel would use a disproportionate amount of processor time to deal
with new packets, resulting in a remote denial of service attack. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2003-0244 to this issue.
A flaw has been found in the "ioperm" system call, which fails to properly
restrict privileges. This flaw can allow an unprivileged local user to
gain read and write access to I/O ports on the system. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-0246 to this issue.
All users should upgrade to these updated packages, which are not
vulnerable to these issues.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To use Red Hat Network to upgrade the kernel, 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 if you are using the default configuration of up2date.
To install kernel packages manually, use "rpm -ivh <package>" and
modify system settings to boot the kernel you have installed. To
do this, edit /boot/grub/grub.conf and change the default entry to
"default=0" (or, if you have chosen to use LILO as your boot loader,
edit /etc/lilo.conf and run lilo)
Do not use "rpm -Uvh" as that will remove your running kernel binaries
from your system. You may use "rpm -e" to remove old kernels after
determining that the new kernel functions properly on your system.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
