-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 495-1 security@debian.org http://www.debian.org/security/ Martin Schulze April 26th, 2004 http://www.debian.org/security/faq - -------------------------------------------------------------------------- Package : kernel-source-2.4.16 kernel-patch-2.4.16-arm kernel-image-2.4.16-lart kernel-image-2.4.16-netwinder kernel-image-2.4.16-riscpc Vulnerability : several vulnerabilities Problem-Type : local Debian-specific: no CVE ID : CAN-2003-0127 CAN-2004-0003 CAN-2004-0010 CAN-2004-0109 CAN-2004-0177 CAN-2004-0178 Bugtraq ID : 10152 Several serious problems have been discovered in the Linux kernel. This update takes care of Linux 2.4.16 for the ARM architecture. The Common Vulnerabilities and Exposures project identifies the following problems that will be fixed with this update: CAN-2003-0127 The kernel module loader allows local users to gain root privileges by using ptrace to attach to a child process that is spawned by the kernel 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 a local attacker could obtain sensitive information (such as cryptographic keys in another worst case) 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 are also fixed by upstream in Linux 2.4.26 and will be fixed in Linux 2.6.6. 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) source 2.4.16-1woody2 2.4.25-3 arm/patch 20040419 20040316 arm/lart 20040419 2.4.25-4 arm/netwinder 20040419 2.4.25-4 arm/riscpc 20040419 2.4.25-4 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.
