-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated kernel packages fix security vulnerabilities Advisory ID: RHSA-2004:255-01 Issue date: 2004-06-17 Updated on: 2004-06-17 Product: Red Hat Enterprise Linux Keywords: Cross references: Obsoletes: RHSA-2004:188 CVE Names: CAN-2004-0427 CAN-2004-0495 CAN-2004-0554 - --------------------------------------------------------------------- 1. Topic: Updated kernel packages for Red Hat Enterprise Linux 3 that fix security vulnerabilities are now available. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 3 - athlon, i386, i686, ia32e, ia64, ppc64, ppc64iseries, ppc64pseries, s390, s390x, x86_64 Red Hat Desktop version 3 - athlon, i386, i686, ia32e, x86_64 Red Hat Enterprise Linux ES version 3 - athlon, i386, i686, ia32e, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - athlon, i386, i686, ia32e, ia64, x86_64 3. Problem description: The Linux kernel handles the basic functions of the operating system. A flaw was found in Linux kernel versions 2.4 and 2.6 for x86 and x86_64 that allowed local users to cause a denial of service (system crash) by triggering a signal handler with a certain sequence of fsave and frstor instructions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0554 to this issue. Another flaw was discovered in an error path supporting the clone() system call that allowed local users to cause a denial of service (memory leak) by passing invalid arguments to clone() running in an infinite loop of a user's program. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0427 to this issue. Enhancements were committed to the 2.6 kernel by Al Viro which enabled the Sparse source code checking tool to check for a certain class of kernel bugs. A subset of these fixes also applies to various drivers in the 2.4 kernel. Although the majority of these resides in drivers unsupported in Red Hat Enterprise Linux 3, the flaws could lead to privilege escalation or access to kernel memory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0495 to these issues. All Red Hat Enterprise Linux 3 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum. These packages contain backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website: https://rhn.redhat.com/help/latest-up2date.pxt 5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 125794 - CAN-2004-0554 local user can get the kernel to hang 125901 - [PATCH] CAN-2004-0554: FPU exception handling local DoS 125968 - last RH kernel affected bug 126121 - CAN-2004-0495 Sparse security fixes backported for 2.4 kernel 6.
