BIND before 9.2.6-P1 and 9.3.x before 9.3.2-P1 allows remote attackers to cause a denial of service (crash) via certain SIG queries, which cause an assertion failure when multiple RRsets are returned.
BIND before 9.2.6-P1 and 9.3.x before 9.3.2-P1 allows remote attackers to cause a denial of service (crash) via a flood of recursive queries, which cause an INSIST failure when the response is received after the recursion queue is empty.
An "incorrect assumption" in the authvalidated validator function in BIND 9.3.0, when DNSSEC is enabled, allows remote attackers to cause a denial of service (named server exit) via crafted DNS packets that cause an internal consistency test (self-check) to fail.
