    1. Topic:
    Several security vulnerabilities exist in the DNS server, 'bind'.

    2. Problem description:
    Various vulnerabilities exist in previous versions of bind:

    • A bug in the processing of NXT records can theoretically allow a remote attacker to gain access to the DNS server as the user running bind (by default, root). This vulnerability does not affect the bind packages that shipped with Red Hat Linux 4.2 and Red Hat Linux 5.2.
    • Several remote denial-of-service attacks are possible; by using abnormal TCP options, causing the DNS server to use many file descriptors, or using special SIG records, it may be possible to crash the DNS server.

      It is recommended that all users of bind upgrade to the latest packages.

      Thanks go to ISC for providing the updated packages.

      3. Bug IDs fixed: (see bugzilla for more information)

      4. Relevant releases/architectures:
      Red Hat Linux 6.1, all architectures

      5. Obsoleted by:
      None

      6. Conflicts with:
      None

      7. RPMs required:

      Intel:

      ftp://updates.Red Hat.com/6.1/i386/

      bind- 8.2.2_P3-1.i386.rpm
      bind- devel-8.2.2_P3-1.i386.rpm
      bind- utils-8.2.2_P3-1.i386.rpm

      Alpha:

      ftp://updates.Red Hat.com/6.0/alpha

      bind- 8.2.2_P3-1.alpha.rpm
      bind-devel-8.2.2_P3-1.alpha.rpm
      bind-utils-8.2.2_P3-1.alpha.rpm

      SPARC:

      ftp://updates.Red Hat.com/6.0/sparc

      bind- 8.2.2_P3-1.sparc.rpm
      bind-devel-8.2.2_P3-1.sparc.rpm
      bind-utils-8.2.2_P3-1.sparc.rpm

      Source:

      ftp://updates.Red Hat.com/6.1/SRPMS

      bind- 8.2.2_P3-1.src.rpm

      8. Solution:
      For each RPM for your particular architecture, run:

      rpm -Uvh filename

      where filename is the name of the RPM.

      Then you will want to restart the named service like so:

      /etc/rc.d/init.d/named stop
      /etc/rc.d/init.d/named start

      9. Verification:

      
       MD5 sum                           Package Name

      These packages are GPG signed by Red Hat, Inc. for security. Our key is available at:
      http://www.Red Hat.com/corp/contac t.html

      You can verify each package with the following command: rpm --checksig filename

      If you only wish to verify that each package has not been corrupted or tampered with, examine only the md5sum with the following command: rpm --checksig --nogpg filename

      Note that you need RPM >= 3.0 to check GnuPG keys.
