Package : kernel-source-2.4.17 kernel-patch-2.4.17-apus kernel-patch-2.4.17-s390 kernel-image-2.4.17-s390
Vulnerability : several vulnerabilities
Problem-Type : local
Debian-specific: no
CVE ID : CAN-2004-0003 CAN-2004-0010 CAN-2004-0109 CAN-2004-0177 CAN-2004-0178
Several serious problems have been discovered in the Linux kernel.
This update takes care of Linux 2.4.17 for the PowerPC/apus and S/390
architectures. The Common Vulnerabilities and Exposures project
identifies the following problems that will be fixed with this update:
CAN-2004-0003
A vulnerability has been discovered in the R128 drive in the Linux
kernel which could potentially lead an attacker to gain
unauthorised privileges. Alan Cox and Thomas Biege developed a
correction for this
CAN-2004-0010
Arjan van de Ven discovered a stack-based buffer overflow in the
ncp_lookup function for ncpfs in the Linux kernel, which could
lead an attacker to gain unauthorised privileges. Petr Vandrovec
developed a correction for this.
CAN-2004-0109
zen-parse discovered a buffer overflow vulnerability in the
ISO9660 filesystem component of Linux kernel which could be abused
by an attacker to gain unauthorised root access. Sebastian
Krahmer and Ernie Petrides developed a correction for this.
CAN-2004-0177
Solar Designer discovered an information leak in the ext3 code of
Linux. In a worst case an attacker could read sensitive data such
as cryptographic keys which would otherwise never hit disk media.
Theodore Ts'o developed a correction for this.
CAN-2004-0178
Andreas Kies discovered a denial of service condition in the Sound
Blaster driver in Linux. He also developed a correction for this.
These problems will also be fixed by upstream in Linux 2.4.26 and
future versions of 2.6.
The following security matrix explains which kernel versions for which
architectures are already fixed.
Architecture stable (woody) unstable (sid)
source 2.4.17-1woody3 2.4.25-3
powerpc/apus 2.4.17-5 2.4.25-2
s390 2.4.17-2.woody.4 2.4.25-2 (and probably 2.4.21-3)
We recommend that you upgrade your kernel packages immediately, either
with a Debian provided kernel or with a self compiled one.
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.
