Red Hat alert RHSA-2003:386-01 (FreeRADIUS)
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated FreeRADIUS packages fix security issue Advisory ID: RHSA-2003:386-01 Issue date: 2003-12-10 Updated on: 2003-12-10 Product: Red Hat Enterprise Linux Keywords: DoS Cross references: Obsoletes: CVE Names: CAN-2003-0967 - --------------------------------------------------------------------- 1. Topic: Updated FreeRADIUS packages are now available that fix a denial of service vulnerability. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux ES version 3 - i386 3. Problem description: FreeRADIUS is an Internet authentication daemon, which implements the RADIUS protocol. It allows Network Access Servers (NAS boxes) to perform authentication for dial-up users. The rad_decode function in FreeRADIUS 0.9.2 and earlier allows remote attackers to cause a denial of service (crash) via a short RADIUS string attribute with a tag, which causes memcpy to be called with a -1 length argument, as demonstrated using the Tunnel-Password attribute. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0967 to this issue. Users of FreeRADIUS are advised to upgrade to these erratum packages containing FreeRADIUS 0.9.3 which is not vulnerable to 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.
