Red Hat Security Advisory 2011-1459-01 - Updated bind97 packages that fix one security issue are now available for Red Hat Enterprise Linux 5. A flaw was discovered in the way BIND handled certain DNS queries, which caused it to cache an invalid record. A remote attacker could use this flaw to send repeated queries for this invalid record, causing the resolvers to exit unexpectedly due to a failed assertion. Users of bind97 are advised to upgrade to these updated packages, which resolve this issue. After installing the update, the BIND daemon will be restarted automatically.
