Debian Security Advisory DSA 479-2                     [e-mail:security@debian.org]

Package        : kernel-image-2.4.18-1-i386
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 2.4.18 for the i386 architecture.
This advisory replaces the i386 part of DSA 479-1 (except for the
i386bf part).  An unfortunate build error caused some of the kernel
packages in DSA 479-1 to be broken.  They are updated with this
advisory.  For completeness below is the original advisory text:

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.

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
architecture are already fixed.  Kernel images in the unstable Debian
distribution (sid) will be fixed soon.

Architecture    stable (woody)     unstable (sid)    removed in sid
source          2.4.18-14.3        2.4.25-3          --
alpha           2.4.18-15          soon              --
i386            2.4.18-13.1        soon              --
i386bf          2.4.18-5woody8     soon              --
powerpc         2.4.18-1woody5     2.4.25-8          2.4.22

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.
