Package        : kernel-source-2.2.20, kernel-image-2.2.20-i386
Vulnerability  : several
Problem-Type   : local, remote
Debian-specific: no
CVE Ids        : CVE-2002-0429 CAN-2003-0001 CAN-2003-0127 CAN-2003-0244 CAN-2003-0246 CAN-2003-0247 CAN-2003-0248 CAN-2003-0364

A number of vulnerabilities have been discovered in the Linux kernel.

- - CVE-2002-0429: The iBCS routines in arch/i386/kernel/traps.c for
  Linux kernels 2.4.18 and earlier on x86 systems allow local users to
  kill arbitrary processes via a a binary compatibility interface
  (lcall)

- - CAN-2003-0001: Multiple ethernet Network Interface Card (NIC) device
  drivers do not pad frames with null bytes, which allows remote
  attackers to obtain information from previous packets or kernel
  memory by using malformed packets

- - CAN-2003-0127: The kernel module loader allows local users to gain
  root privileges by using ptrace to attach to a child process that is
  spawned by the kernel

- - CAN-2003-0244: The route cache implementation in Linux 2.4, and the
  Netfilter IP conntrack module, allows remote attackers to cause a
  denial of service (CPU consumption) via packets with forged source
  addresses that cause a large number of hash table collisions related
  to the PREROUTING chain

- - CAN-2003-0246: The ioperm system call in Linux kernel 2.4.20 and
  earlier does not properly restrict privileges, which allows local
  users to gain read or write access to certain I/O ports.

- - CAN-2003-0247: vulnerability in the TTY layer of the Linux kernel
  2.4 allows attackers to cause a denial of service ("kernel oops")

- - CAN-2003-0248: The mxcsr code in Linux kernel 2.4 allows attackers
  to modify CPU state registers via a malformed address.

- - CAN-2003-0364: The TCP/IP fragment reassembly handling in the Linux
  kernel 2.4 allows remote attackers to cause a denial of service (CPU
  consumption) via certain packets that cause a large number of hash
  table collisions

This advisory provides updated 2.2.20 kernel source, and binary kernel
images for the i386 architecture.  Other architectures and kernel
versions will be covered by separate advisories.

For the stable distribution (woody) on the powerpc architecture, these
problems have been fixed in kernel-source-2.2.20 version
2.2.20-5woody2 and kernel-image-i386 version 2.2.20-5woody3.

For the unstable distribution (sid) these problems are fixed in
kernel-source-2.2.25 and kernel-image-2.2.25-i386 version 2.2.25-2.

We recommend that you update your kernel packages.

NOTE: A system reboot will be required immediately after the upgrade
in order to replace the running kernel.  Remember to read carefully
and follow the instructions given during the kernel upgrade process.

NOTE: These kernels are not binary-compatible with the previous
version.  Any loadable modules will need to be recompiled in order to
work with the new kernel.

Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
