"Updated freeradius packages fixes security vulnerabilities :

It was found that the unix module ignored the password expiration
setting in /etc/shadow. If FreeRADIUS was configured to use this
module for user authentication, this flaw could allow users with an
expired password to successfully authenticate, even though their
access should have been denied (CVE-2011-4966).

Stack-based buffer overflow in the cbtls_verify function in FreeRADIUS
2.1.10 through 2.1.12, when using TLS-based EAP methods, allows remote
attackers to cause a denial of service (server crash) and possibly
execute arbitrary code via a long not after timestamp in a client
certificate (CVE-2012-3547)."
