Updated iproute packages that close a locally-exploitable denial of servicevulnerability are now available.. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated iproute packages fix local security vulnerability Advisory ID: RHSA-2003:316-01 Issue date: 2003-11-24 Updated on: 2003-11-24 Product: Red Hat Linux Keywords: DoS Cross references: Obsoletes: CVE Names: CAN-2003-0856 - --------------------------------------------------------------------- 1. Topic: Updated iproute packages that close a locally-exploitable denial of service vulnerability are now available. 2. Relevant releases/architectures: Red Hat Linux 7.1 - i386 Red Hat Linux 7.1 for iSeries (64 bit) - ppc Red Hat Linux 7.1 for pSeries (64 bit) - ppc Red Hat Linux 7.2 - i386, ia64 Red Hat Linux 7.3 - i386 Red Hat Linux 8.0 - i386 Red Hat Linux 9 - i386 3. Problem description: The iproute package contains advanced IP routing and network device configuration tools. Herbert Xu reported that iproute can accept spoofed messages sent on the kernel netlink interface by other users on the local machine. This could lead to a local denial of service attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0856 to this issue. Users of iproute should upgrade to these erratum packages, which contain a patch that checks that netlink messages actually came from the kernel. 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 usewildcards (*.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: 5.
