                    Fedora Legacy Update Advisory

    Synopsis: Updated freeradius packages fix security flaws
    Advisory ID: FLSA:2187
    Issue date: 2005-02-01
    Product: Fedora Core
    Keywords: Bugfix
    Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2187
    CVE Names: CAN-2004-0938 CAN-2004-0960 CAN-2004-0961
    -----------------------------------------------------------------------

    1. Topic:

    Updated freeradius packages that fix a number of denial of service
    vulnerabilities as well as minor bugs are now available.

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

    2. Relevant releases/architectures:

    Fedora Core 1 - i386

    3. Problem description:

    A number of flaws were found in FreeRADIUS versions prior to 1.0.1. An
    attacker who is able to send packets to the server could construct
    carefully constructed packets in such a way as to cause the server to
    consume memory or crash. The Common Vulnerabilities and Exposures
    project (cve.mitre.org) has assigned the names CAN-2004-0938,
    CAN-2004-0960, and CAN-2004-0961 to these issues.

    Please note that the pam config file included in these packages was
    renamed to /etc/pam.d/radiusd.

    Users of FreeRADIUS should update to these erratum packages that contain
    FreeRADIUS 1.0.1, which is not vulnerable to these issues and also
    corrects a number of bugs.

    4. Solution:

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

    To update all RPMs for your particular architecture, run:

    rpm -Fvh [filenames]

    where [filenames] is a list of the RPMs you wish to upgrade. Only those
    RPMs which are currently installed will be updated. Those RPMs which
    are not installed but included in the list will not be updated. Note
    that you can also use wildcards (*.rpm) if your current directory *only*
    contains the desired RPMs.

    Please note that this update is also available via yum and apt. Many
    people find this an easier way to apply updates. To use yum issue:

    yum update

    or to use apt:

    apt-get update; apt-get upgrade

    This will start an interactive process that will result in the
    appropriate RPMs being upgraded on your system. This assumes that you
    have yum or apt-get configured for obtaining Fedora Legacy content.
    Please visit http://www fedoralegacy.org/docs for directions on how to
    configure yum and apt-get.

    5. Bug IDs fixed:

    http://bugzilla.fedora.us - 2187 - Freeradius < 1.0.1 DoS and remote crash

    6. RPMs required:

    Fedora Core 1:

    These packages are GPG signed by Fedora Legacy for security. Our key is
    available from http://www.fedoralegacy org/about/security.php

    You can verify each package with the following command:

         rpm --checksig -v <filename>

    If you only wish to verify that each package has not been corrupted or
    tampered with, examine only the sha1sum with the following command:

         sha1sum <filename>
