Package	:	kernel-patch-2.4.18-powerpc
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 covers only the powerpc architecture. Other
architectures will be covered by separate advisories.

For the stable distribution (woody) on the powerpc architecture,
these problems have been fixed in version 2.4.18-1woody1.

For the unstable distribution (sid) these problems are fixed in
version 2.4.20-2.

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.

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.
