                            SCO Security Advisory

    Subject: UnixWare 7.1.1 : Bind: cache poisoning BIND 8 prior to 8.3.7 and BIND 8.4.x prior 8.4.2
    Advisory number: CSSA-2003-SCO.33.1
    Issue date: 2003 December 01
    Cross reference: sr886768 fz528464 erg712479 CAN-2003-0914
    ______________________________________________________________________________

    1. Problem Description

             UPDATED: Maintenance Pack 4 is now prerequisite. Previous releases
                      required update pack 2.

             UnixWare 7.1.3 is unaffected by this issue because the
             version of bind included in UnixWare 7.1.3 is 9.2.1.

             Open UNIX is also unaffected by this issue because the version
             of bind in Open UNIX 8.0.0 is 9.1.0.

             CERT/CC Incident Note VU#734644

             BIND is an implementation of the Domain Name System (DNS)
             protocols. Successful exploitation of this vulnerability
             may result in a temporary denial of service.

             The Common Vulnerabilities and Exposures project (cve.mitre.org)
             has assigned the name CAN-2003-0914 to this issue.

    2. Vulnerable Supported Versions

            System Binaries
            ----------------------------------------------------------------------
            UnixWare 7.1.1 /usr/sbin/addr
                                            /usr/sbin/dig
                                            /usr/sbin/dnskeygen
                                            /usr/sbin/dnsquery
                                            /usr/sbin/host
                                            /usr/sbin/in.named
                                            /usr/sbin/irpd
                                            /usr/sbin/mkservdb
                                            /usr/sbin/named-bootconf
                                            /usr/sbin/named-bootconf.pl
                                            /usr/sbin/named-xfer
                                            /usr/sbin/ndc
                                            /usr/sbin/nslookup
                                            /usr/sbin/nsupdate

    3. Solution

            The proper solution is to install the latest packages.

    4. UnixWare 7.1.1

            4.1 UnixWare 7.1.1 Maintenance Pack 4 is a prerequisite.

            4.2 Location of Fixed Binaries

            ftp://ftp.sco.com/pub/updates/UnixWare/CSSA-2003-SCO.33

            4.3 Verification

            MD5 (erg712479b.Z) = d81ecd04dccda1fc76ee41947c5593d3

            md5 is available for download from
                    ftp://ftp.sco.com/pub/security/tools

            4.3 Installing Fixed Binaries

            Upgrade the affected binaries with the following sequence:

            1. Download the erg712479b.Z file to the /tmp directory on your machine.

            2. As root, uncompress the file and add the package to your system
               using these commands:

                    $ su
                    Password: <type your root password>
                    # uncompress /tmp/erg712479b.Z
                    # pkgadd -d /tmp/erg712479b
                    # rm /tmp/erg712479b

            Alternatively, this SLS package may be installed in quiet mode,
            that is, without displaying the release notes and asking for
            confirmation. To do this, use these commands:

                    $ su
                    Password: <type your root password>
                    # uncompress /tmp/erg712479b.Z
                    # pkgadd -qd /tmp/erg712479b all
                    # rm /tmp/erg712479b

            3. There is no need to reboot the system after installing this package.

            Removal Instructions
            --------------------

            1. As root, remove the package using these commands:

                    $ su
                    Password: <type your root password>
                    # pkgrm erg712479

            2. There is no need to reboot the system after removing this package
