Debian Security Advisory DSA 336-2 security@...ian.org
http://www.debian.org/security/ Matt Zimmerman
June 29th, 2003 http://www.debian.org/security/faq
- --------------------------------------------------------------------------
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-2003-0364 CAN-2002-1380
NOTE: This advisory is being released as a factual correction to
DSA-336-1. In an administrative error, DSA-336-1 listed several CVE
names which did not, in fact, apply to Linux 2.2.20, and omitted one
vulnerability which was fixed in the updated packages. The packages
are (and were) correct, and remain unchanged. The package changelog
contains the correct information. This advisory provides updated
information only.
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-2003-0364: 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
- - CAN-2002-1380: Linux kernel 2.2.x allows local users to cause a
denial of service (crash) by using the mmap() function with a
PROT_READ parameter to access non-readable memory pages through the
/proc/pid/mem interface.
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.
