Red Hat Security Advisory Synopsis: Updated radiusd-cistron packages are available Advisory ID: RHSA-2002:030-08 Issue date: 2002-02-20 Updated on: 2002-03-04 Product: Red Hat Powertools Keywords: radius radiusd malformed packet Cross references: Obsoletes: - --------------------------------------------------------------------- 1. Topic: Updated radiusd-cistron packages, which fix various security issues, are now available. 2. Relevant releases/architectures: Red Hat Powertools 7.0 - alpha, i386 Red Hat Powertools 7.1 - alpha, i386 3. Problem description: The radiusd-cistron package contains a server daemon for the Remote Authentication Dial-In User Server (RADIUS) client/server security protocol. Various vulnerabilities have been found in Cistron RADIUS as well as other RADIUS servers and clients. In versions of Cistron RADIUS 1.6.5 and earlier, malformed packets could be used to gain additional privileges. All users of Cistron RADIUS are advised to upgrade to version 1.6.6, which is not vulnerable to these issues. Pay special attention to the installation instructions in the Solution section as they vary significantly from the usual update method. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is currently not available through Red Hat Network. Due to a bug in previously released versions, the original package must be removed, and the new package must be installed to apply this update (as root): # /sbin/service radiusd stop # /sbin/chkconfig --del radiusd # rpm -e --noscripts radiusd-cistron # rpm -ivh radiusd-cistron-1.6.6-2.[arch].rpm where [arch] is the architecture. 5.
