bind: bind9: Potential memory usage beyond configured limits

A DNSSEC validating resolver that is under a random subdomain attack against a DNSSEC-signed zone can suffer from runaway memory usage. The attacker needs to be able to send queries faster than the resolver can perform validation. The increased memory usage can be orders of magnitude beyond the...

bind: bind9: Cache poisoning via label count discrepancy, RRSIG, wildcards

It is possible for an attacker's zone to respond to a query with an RRSIG that has a smaller number of labels than the zone in which the RRSIG is contained. This causes named to produce a wildcard name for a zone that is shorter than the attacker's zone, which can result in cache poisoning. For...

bind9: bind: BIND 9: Denial of Service via 16-bit length truncation in DNS negative cache handling

A flaw was found in bind9's named component. A remote attacker, by sending a specially crafted DNS negative answer of exactly 65536 bytes from an authoritative server, can cause a 16-bit length truncation. This results in a zero-byte negative cache entry. When named attempts to read this invalid...
