    Errata
    ======

    This advisory incorrectly described FreeRADIUS versions as being
    vulnerable to a remote compromise. After further verifications, it
    appears to only result in potential Denial of Service. The SQL injection
    issue is not affected by this. Many thanks to Nicolas Baradakis for
    bringing this to our attention.

    The corrected sections appear below.

    Synopsis
    ========

    The FreeRADIUS server is vulnerable to an SQL injection attack and a
    buffer overflow, possibly resulting in disclosure and modification of
    data and Denial of Service.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-dialup/freeradius < 1.0.2-r4 >= 1.0.2-r4

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

    Primoz Bratanic discovered that the sql_escape_func function of
    FreeRADIUS may be vulnerable to a buffer overflow (BID 13541). He also
    discovered that FreeRADIUS fails to sanitize user-input before using it
    in a SQL query, possibly allowing SQL command injection (BID 13540).

    Impact
    ======

    By supplying carefully crafted input, a malicious user could cause an
    SQL injection or a buffer overflow, possibly leading to the disclosure
    and the modification of sensitive data or Denial of Service by crashing
    the server.

    Resolution
    ==========

    All FreeRADIUS users should upgrade to the latest available version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-1.0.2-r4"

    Availability
    ============

    This GLSA and any updates to it are available for viewing at
    the Gentoo Security Website:

    confidentiality and security of our users machines is of utmost
    importance to us. Any security concerns should be addressed to
