A denial of service flaw was found in the way BIND versions as shipped with RHEL 6 handled DNSSEC validation. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response. This issue does not affect the upstream versions of BIND. This issue does not affect BIND configurations which have DNSSEC validation turned off.
Statement: This issue affected only the BIND versions as shipped with Red Hat Enterprise Linux 6. This issue did not affect any upstream versions of BIND. This issue does not affect BIND configurations which have DNSSEC validation turned off.
