modules/rlmunix/rlmunix.c in FreeRADIUS before 2.2.0, when unix mode is enabled for user authentication, does not properly check the password expiration in /etc/shadow, which allows remote authenticated users to authenticate using an expired password.

DISPUTED Buffer overflow in the SMBConnectServer function in FreeRadius 1.1.3 and earlier allows attackers to execute arbitrary code related to the server desthost field of an SMBHandleType instance. NOTE: the impact of this issue has been disputed by a reliable third party and the vendor, who states that exploitation is limited "only to local administrators who have write access to the server configuration files." CVE concurs with the dispute.
