The remote Redhat Enterprise Linux 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2013:0134 advisory.

    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)

    * Due to invalid syntax in the PostgreSQL admin schema file, the FreeRADIUS     PostgreSQL tables failed to be created. With this update, the syntax has     been adjusted and the tables are created as expected. (BZ#818885)

    * FreeRADIUS has a thread pool that dynamically grows based on load. If     multiple threads using the rlm_perl() function are spawned in quick     succession, the FreeRADIUS server sometimes terminated unexpectedly with a     segmentation fault due to parallel calls to the rlm_perl_clone()     function. With this update, a mutex for the threads has been added and the     problem no longer occurs. (BZ#846475)

    * The man page for rlm_dbm_parser was incorrectly installed as     rlm_dbm_parse, omitting the trailing r. The man page now correctly     appears as rlm_dbm_parser. (BZ#781877)

    All users of freeradius2 are advised to upgrade to these updated packages,     which contain backported patches to correct these issues. They are also     advised to check for RPM backup files ending in .rpmnew or .rpmsave     under the /etc/raddb/ directory after the update because the FreeRADIUS     server will attempt to load every file it finds in its configuration     directory. The extra files will often cause the wrong configuration values     to be applied resulting in either unpredictable behavior or the failure of     the server to initialize and run.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
