Hi Guys! Le mercredi 14 avril 2004 23h58 (+0200), Martin Schulze crivait : An unfortunate build error caused some of the kernel packages in DSA 479-1 to be broken.

Re: [SECURITY] [DSA 479-2] New Linux 2.4.18 packages fix local root exploit (i386)
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.

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.
