Updated bind packages that fix one security issue are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System base score, which gives a detailed severity rating, is available from the CVE link in the References section. Description The Berkeley Internet Name Domain is an implementation of the Domain Name System protocols. BIND includes a DNS server ; a resolver library ; and tools for verifying that the DNS server is operating correctly. DNS64 is used to automatically generate DNS records so IPv6 based clients can access IPv4 systems through a NAT64 server. A flaw was found in the DNS64 implementation in BIND. If a remote attacker sent a specially-crafted query to a named server, named could exit unexpectedly with an assertion failure. Note that DNS64 support is not enabled by default. Users of bind are advised to upgrade to these updated packages, which correct this issue. After installing the update, the BIND daemon will be restarted automatically.
