-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 336-2 security@debian.org http://www.debian.org/security/ Matt Zimmerman June 29th, 2003 http://www.debian.org/security/faq - -------------------------------------------------------------------------- Package : kernel-source-2.2.20, kernel-image-2.2.20-i386 Vulnerability : several Problem-Type : local, remote Debian-specific: no CVE Ids : CVE-2002-0429 CAN-2003-0001 CAN-2003-0127 CAN-2003-0364 CAN-2002-1380 NOTE: This advisory is being released as a factual correction to DSA-336-1. In an administrative error, DSA-336-1 listed several CVE names which did not, in fact, apply to Linux 2.2.20, and omitted one vulnerability which was fixed in the updated packages. The packages are (and were) correct, and remain unchanged. The package changelog contains the correct information. This advisory provides updated information only. A number of vulnerabilities have been discovered in the Linux kernel. - - CVE-2002-0429: The iBCS routines in arch/i386/kernel/traps.c for Linux kernels 2.4.18 and earlier on x86 systems allow local users to kill arbitrary processes via a a binary compatibility interface (lcall) - - CAN-2003-0001: Multiple ethernet Network Interface Card (NIC) device drivers do not pad frames with null bytes, which allows remote attackers to obtain information from previous packets or kernel memory by using malformed packets - - 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-2003-0364: The TCP/IP fragment reassembly handling in the Linux kernel 2.4 allows remote attackers to cause a denial of service (CPU consumption) via certain packets that cause a large number of hash table collisions - - CAN-2002-1380: Linux kernel 2.2.x allows local users to cause a denial of service (crash) by using the mmap() function with a PROT_READ parameter to access non-readable memory pages through the /proc/pid/mem interface. This advisory provides updated 2.2.20 kernel source, and binary kernel images for the i386 architecture. Other architectures and kernel versions will be covered by separate advisories. For the stable distribution (woody) on the powerpc architecture, these problems have been fixed in kernel-source-2.2.20 version 2.2.20-5woody2 and kernel-image-i386 version 2.2.20-5woody3. For the unstable distribution (sid) these problems are fixed in kernel-source-2.2.25 and kernel-image-2.2.25-i386 version 2.2.25-2. We recommend that you update your kernel packages. NOTE: A system reboot will be required immediately after the upgrade in order to replace the running kernel. Remember to read carefully and follow the instructions given during the kernel upgrade process. NOTE: These kernels are not binary-compatible with the previous version. Any loadable modules will need to be recompiled in order to work with the new kernel. 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.
