       Red Hat, Inc. Security Advisory

Synopsis:    Security problems in bind
Advisory ID:    RHSA-1999:054-01
Issue date:    1999-11-11
Updated on:    1999-11-11

1. Topic:

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

2. Relevant releases/architectures:

Red Hat Linux 4.x, all platforms
Red Hat Linux 5.x, all platforms
Red Hat Linux 6.x, all platforms

3. 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.

4. Solution:

For each RPM for your particular architecture, run:
    rpm -Uvh <filename>
where filename is the name of the RPM.

5. Bug IDs fixed (http://developer.redhat.com/bugzilla for more info):
