Red Hat Security Advisory

Synopsis: Important: freeradius security update
Advisory ID: RHSA-2006:0271-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2006-0271.html
Issue date: 2006-04-04
Updated on: 2006-04-04
Product: Red Hat Enterprise Linux
CVE Names: CVE-2006-1354 CVE-2005-4744
- ---------------------------------------------------------------------

1. Summary:

Updated freeradius packages that fix an authentication weakness are now
available.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64

3. Problem description:

FreeRADIUS is a high-performance and highly configurable free RADIUS server
designed to allow centralized authentication and authorization for a network.

A bug was found in the way FreeRADIUS authenticates users via the MSCHAP V2
protocol. It is possible for a remote attacker to authenticate as a victim
by sending a malformed MSCHAP V2 login request to the FreeRADIUS server.
(CVE-2006-1354)

Please note that FreeRADIUS installations not using the MSCHAP V2 protocol
for authentication are not vulnerable to this issue.

A bug was also found in the way FreeRADIUS logs SQL errors from the
sql_unixodbc module. It may be possible for an attacker to cause FreeRADIUS
to crash or execute arbitrary code if they are able to manipulate the SQL
database FreeRADIUS is connecting to. (CVE-2006-4744)

Users of FreeRADIUS should update to these erratum packages, which contain
backported patches and are not vulnerable to these issues.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/):

167676 - CVE-2005-4744 Multiple freeradius security issues
186083 - CVE-2006-1354 FreeRADIUS authentication bypass
