Synopsis

Important: bind security update

Type/Severity

Security Advisory: Important

Topic

Updated bind packages that fix one security issue are now available for
Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

Description

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain
Name System (DNS) protocols. BIND includes a DNS server (named); a resolver
library (routines for applications to use when interfacing with DNS); and
tools for verifying that the DNS server is operating correctly.

It was discovered that named did not invalidate previously cached SIG
records when adding an NCACHE record for the same entry to the cache. A
remote attacker allowed to send recursive DNS queries to named could use
this flaw to crash named. (CVE-2010-3613)

All BIND users are advised to upgrade to these updated packages, which
contain a backported patch to resolve this issue. After installing the
update, the BIND daemon (named) will be restarted automatically.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
