                Internet Software Consortium Security Advisory.
                             Status Update
                             5 March 2003

        BIND 9.2.2 was released which contains fixes for previously
        announced vulnerabilities.

        These were a remote buffer overflow documented in CERT advisory
        [CERT CA-2002-19] and enforcement of the minimum OpenSSL version
        [CERT CA-2002-23].

        http://www.cert.org/advisories/CA-2002-19.html
        http://www.cert.org/advisories/CA-2002-23.html

        [CERT CA-2002-19]:

        BIND 9.2.0 and BIND 9.2.1 needs to be upgraded if you have not
        already applied the workaround listed in [CERT CA-2002-19] and
        you enabled libbind by specifying "configure --enable-libbind"
        when you built BIND 9.2.0 or BIND 9.2.1.

        [CERT CA-2002-23]:

        BIND 9.[01].x needs to be upgraded if you have not applied the
        workaround listed in [CA-2002-23]. BIND 9.2.2 enforces a
        minimum OpenSSL version at compile time.

        BIND 9.2.0 and BIND 9.2.1 need to be upgraded if you built BIND
        with a vulnerable version of OpenSSL, "configure --with-openssl".
        BIND 9.2.2 enforces a minimum OpenSSL version at compile time.

        You can test to see if BIND was built with OpenSSL by running:

                dnssec-keygen -a rsa -b 512 -n zone foo

        If the command returns an error message which contains "built with
        no crypto support" then BIND was NOT linked against OpenSSL. This
        does NOT check the OpenSSL version in use.

        If you are in doubt about your current BIND status upgrade.

        The current BIND version can be found via:
