Insight
FreeRADIUS is an open-source Remote Authentication Dial-In User Service (RADIUS) server which allows RADIUS clients to perform authentication against the RADIUS server. The RADIUS server may optionally perform accounting of its operations using the RADIUS protocol.
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)
This update also fixes the following bugs:
* After log rotation, the freeradius logrotate script failed to reload the radiusd daemon and log messages were lost. This update has added a command to the freeradius logrotate script to reload the radiusd daemon and the radiusd daemon re-initializes and reopens its log files after log rotation as expected. (BZ#787111)
* The radtest script with the 'eap-md5' option failed because it passed the IP family argument when invoking the radeapclient utility and the radeapclient utility did not recognize the IP family. The radeapclient utility now recognizes the IP family argument and radtest now works with eap-md5 as expected. (BZ#846476)
* Previously, freeradius was compiled without the '--with-udpfromto' option. Consequently, with a multihomed server and explicitly specifying the IP address, freeradius sent the reply with the wrong IP source address.
With this update, freeradius has been built with the '--with-udpfromto"' configuration option and the RADIUS reply is always sourced from the IP address the request was sent to. (BZ#846471)
