RHBA-2012:0196 - Bug Fix Advisory

Topic

Updated freeradius2 packages that fix several bugs and add an enhancement are
now available for Red Hat Enterprise Linux 5.

Description

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
via the RADIUS protocol.

The freeradius2 packages have been upgraded to upstream version 2.1.12, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#609633)

These updated freeradius2 packages provide fixes for the following bugs:

• The documentation of command-line arguments was incomplete and in some cases

erroneous; some commands did not have a man page. The man pages and help output
were updated to correct these deficiencies. (BZ#546583)

• Previously, freeradius2 did not respect the core dump configuration flag.

Consequently, the radiusd process did not produce a core dump file when it
terminated unexpectedly with a segmentation fault. With this update the problem
has been fixed, and now if radiusd aborts, a core dump is now generated if the
core dump flag is enabled. (BZ#602567)

• The freeradius-pam-conf configuration file, /etc/pam.d/radiusd, referenced a

non-existent pam configuration "password-auth". This has been fixed to refer to
"system-auth". (BZ#658508)

• The previous version of freeradius generated its temporary SSL certificates

the first time the server was run with the "-X" debug flag. Now the temporary
certificates are created the first time the freeradius RPM is installed. It is
no longer necessary to run the server in debug mode to create the initial
certificates. (BZ#756442)

• The radtest command-line argument to request the PPP hint option was not

parsed correctly. Consequently, radclient did not add the PPP hint to the
request packet and the test failed. This update corrects the problem and radtest
now functions as expected. (BZ#760193)

In addition, these updated freeradius2 packages provide the following
enhancement:

• The radtest tool did not send a Message-Authenticator by default in an

Access-Request. Consequently, radtest could not connect to a RADIUS server if it
required the authenticator as per RFC 5080. With this update the problem has
been fixed, and now the Message-Authenticator is always sent. (BZ#630072)

Users are advised to upgrade to these updated freeradius2 packages, which fix
these bugs and add this enhancement.
