Some masochistic part of me really wants to know how you can twist a broken
package build, missing a bunch of files, into a security weakness.

Off course! And I don't ask to blame anybody!

I'm just curious to know the details, so it may be usefull to me too
when I'm compiling my own kernel for my whole network.

Hi Guys!

 An unfortunate build error caused some of the kernel packages in
 DSA 479-1 to be broken.

When you have time, could you please tell people how could that happen?
Doesn't packaging process has any check for compile or build error?

I don't want to criticize Debian: I love Debian, and especialy its
we won't hide problems clause... :)

Hi,

I got the mail, and happy to know that you keep the good work. But when I
did 'apt-get update', there was no change in http://security.debian.org
files. Is it possible to make sure the files are updated before sending the
announcement?

I know that each mail has the link for all the files... but many people
automate the updates of the machine, which means that they won't get the
updates till the mirror files will be updated.

Regards,

Lior Kaplan

 Debian Security Advisory DSA 479-2 [EMAIL PROTECTED]

 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.

 Architecturestable (woody) unstable (sid)removed in sid
 source  2.4.18-14.32.4.25-3  --
 alpha   2.4.18-15  soon  --
 i3862.4.18-13.1soon  --
 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.
