Detail
| Problem Description: Updated freeradius packages that fix a security issue are now available for Red Hat Enterprise Linux 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 3. Description: FreeRADIUS is a high-performance and highly configurable free Remote Authentication Dial In User Service (RADIUS) server, designed to allow centralized authentication and authorization for a network. An input validation flaw was discovered in the way FreeRADIUS decoded specific RADIUS attributes from RADIUS packets. A remote attacker could use this flaw to crash the RADIUS daemon (radiusd) via a specially-crafted RADIUS packet. (CVE-2009-3111) Users of FreeRADIUS are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, radiusd will be restarted automatically. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 521912 - CVE-2009-3111 FreeRADIUS: Missing check for Tunnel-Password attributes with zero length (DoS) -- re-appearance of CVE-2003-0967 |

| 57897 | FreeRADIUS radiusd rad_decode Function Zero-length Tunnel-Password Attribute ... |
| 2850 | FreeRADIUS Tagged Attribute Handling DoS FreeRADIUS 0.9.2, and earlier, contains a flaw that may allow a remote denial of service. The issue is triggered when reception of a malformed packet sent to the service occurs, and will result in loss of availability for the service. It is possible to crash the service due to a NULL pointer dereference bug, which can be exploited by sending an "Access-Request" packet containing a "Tunnel-Password" attribute. |
