    Synopsis
    ========

    Multiple Denial of Service vulnerabilities were found and fixed in
    FreeRADIUS.

    Background
    ==========

    FreeRADIUS is an open source RADIUS authentication server
    implementation.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-dialup/freeradius < 1.0.1 >= 1.0.1

    Description
    ===========

    There are undisclosed defects in the way FreeRADIUS handles incorrect
    received packets.

    Impact
    ======

    A remote attacker could send specially-crafted packets to the
    FreeRADIUS server to deny service to other users by crashing the
    server.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All FreeRADIUS users should upgrade to the latest version:

        # emerge sync

        # emerge -pv ">=net-dialup/freeradius-1.0.1"
        # emerge ">=net-dialup/freeradius-1.0.1"
