Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

CVE-2009-4022 bind: cache poisoning using not validated DNSSEC
responses

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)

After installing the update, the BIND daemon (named) will be restarted
automatically.
