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
Keywords: bind named NXT solinger fdmax
Cross references: http://www.isc.org/products/BIND/bind-security-19991108.html
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
where filename is the name of the RPM.
