RHSA-2009:1451 - Moderate: freeradius security update
Synopsis
Moderate: freeradius security update
Type/Severity
Security Advisory Moderate
Topic
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.
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.
Solution
Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
