Red Hat alert RHSA-2003:418-01 (kernel)
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated IA64 kernel packages resolve security vulnerability Advisory ID: RHSA-2003:418-01 Issue date: 2004-01-05 Updated on: 2004-01-05 Product: Red Hat Enterprise Linux Keywords: Cross references: Obsoletes: RHSA-2003:368 CVE Names: CAN-2003-0985 - --------------------------------------------------------------------- 1. Topic: Updated kernel packages are now available that fix a security vulnerability which may allow local users to gain root privileges. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 3. Problem description: The Linux kernel handles the basic functions of the operating system. Paul Starzetz discovered a flaw in bounds checking in mremap() in the Linux kernel versions 2.4.23 and previous which may allow a local attacker to gain root privileges. No exploit is currently available; however, it is believed that this issue is exploitable (although not trivially.) The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0985 to this issue. All users are advised to upgrade to these errata packages, which contain a backported security patch that corrects this issue. Red Hat would like to thank Paul Starzetz from ISEC for disclosing this issue as well as Andrea Arcangeli and Solar Designer for working on the patch. 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.
