RedHat: Moderate: bind security update RHSA-2009:1620-01
Summary
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.
Michael Sinatra discovered that BIND was incorrectly caching responses
without performing proper DNSSEC validation, when those responses were
received during the resolution of a recursive client query that requested
DNSSEC records but indicated that checking should be disabled. A remote
attacker could use this flaw to bypass the DNSSEC validation check and
perform a cache poisoning attack if the target BIND server was receiving
such client queries. (CVE-2009-4022)
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.
Summary
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
