Package : kernel-source-2.4.19 kernel-patch-2.4.19-mips 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 MIPS architecture. The Common Vulnerabilities and Exposures project identifies the following problems that will be fixed with this update:


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


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.


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.


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.


Andreas Kies discovered a denial of service condition in the Sound
Blaster driver in Linux.  He also developed a correction for this.

These problems are also 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 and which will be removed instead.

Architecture stable (woody) unstable (sid) remove in sid source 2.4.19-4.woody2 2.4.25-3 2.4.19-11 mips 2.4.19-0.020911.1.woody4 2.4.25-0.040415.1 2.4.19-0.020911.8 h 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.
