Description

The Berkeley Internet Name Domain (BIND) is an implementation of the DomainName System (DNS) protocols. BIND includes a DNS server (named); a resolverlibrary (routines for applications to use when interfacing with DNS); andtools for verifying that the DNS server is operating correctly.Michael Sinatra discovered that BIND was incorrectly caching responseswithout performing proper DNSSEC validation, when those responses werereceived during the resolution of a recursive client query that requestedDNSSEC records but indicated that checking should be disabled. A remoteattacker could use this flaw to bypass the DNSSEC validation check andperform a cache poisoning attack if the target BIND server was receivingsuch client queries. (CVE-2009-4022)All BIND users are advised to upgrade to these updated packages, whichcontain a backported patch to resolve this issue. After installing theupdate, the BIND daemon (named) will be restarted automatically.
