Type:	Security Advisory
Severity:	Moderate
Issued on:	2009-09-17
Last updated on:	2009-09-17
Affected Products:	RHEL Desktop Workstation (v. 5 client) Red Hat Enterprise Linux (v. 5 server) Red Hat Enterprise Linux EUS (v. 5.4.z server)
CVEs (cve.mitre.org):	CVE-2009-3111

Details

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.

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.

This update is available via Red Hat Network. Details on how to use
