bind: bind9: Unexpected exit with NSEC and NSEC3 both present

If a provably insecure domain is covered by both an NSEC and NSEC3 record at the parent, and there exist an RRSIG for only one of these types, then BIND may exit unexpectedly with an assertion while validating this proof...

bind: BIND 9 server memory exhaustion during GSS-API TKEY negotiation

A flaw was found in BIND. A remote attacker can exploit this vulnerability by sending maliciously-constructed packets to BIND servers configured for TKEY-based authentication via GSS-API Generic Security Service Application Program Interface tokens. This can lead to excessive memory consumption,...

bind: BIND: Denial of Service via specially crafted DNS messages

A flaw was found in the bind component, specifically within the named daemon. This vulnerability allows a remote attacker to send specially crafted Domain Name System DNS messages. These messages, which use unusual classes or meta-classes, can trigger assertion failures in the named daemon when...

bind: bind: Denial of Service via long query names in RPZ processing

A flaw was found in BIND. A remote attacker can send specially crafted, excessively long query names to a resolver configured with Response Policy Zones RPZ and wildcard policies. Improper handling of the resulting error condition can cause the service to terminate unexpectedly, leading to a Deni...

bind: BIND: Denial of Service via malformed DNS64 responses

A flaw was found in BIND. When a resolver is configured to use DNS64, a specially crafted, malformed answer from an authoritative server can cause the named process to exit unexpectedly. This can lead to a Denial of Service DoS for clients relying on the affected resolver...

bind: BIND: Denial of Service via crafted DNSSEC reply

A flaw was found in BIND. A remote attacker, by sending a specially crafted DNSSEC-signed authoritative zone reply, can trigger an unexpected program exit in the validating resolver. This can lead to a Denial of Service DoS for the affected BIND resolver...

389-ds-base: 389-ds: anonymous LDAP client can defeat SELFDN ACI bind-rule checks via empty bind DN

A flaw was found in 389 Directory Server. The SELFDN ACI bind-rule evaluator incorrectly matches an anonymous LDAP client's empty bind DN against an empty stored attribute value, allowing an unauthenticated client to satisfy access control checks intended to require a matching authenticated...
