UBUNTU-CVE-2026-71194

In OpenStack Designate before 22.0.2, the mDNS handler performs pool-blind lookups when resolving record queries and NOTIFY requests. When two zones with the same name exist across different pools, the lookup fails with a deterministic error, causing the handler to return REFUSED for all DNS...

bind: bind9: Incorrect acceptance of NSEC3 records

BIND may accept incorrect child-zone NSEC3 records as valid, which could allow an attacker to forge authenticated NXDOMAIN responses...

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...

bind: bind9: DNSSEC Validation Bypass via Out-of-Zone NSEC Next Field

The BIND resolver accepts validly-signed NSEC records where the "Next Domain Name" field points outside the signer's zone...

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...

bind9: bind: Potential wildcard CNAME RPZ policy bypass

A flaw was found in BIND 9, a widely used Domain Name System DNS software. A remote attacker could exploit this by sending specially crafted, excessively long DNS queries. This could bypass Response Policy Zone RPZ rules, which are designed to block access to malicious domains, and potentially...

bind: bind9: Record ordering based unexpected exit with CNAME or DNAME

The issue is unexpected program termination based on ordering and/or specific content in responses to queries for CNAME or DNAME, and A records. Specifically, if a client queries for a DNAME and A record below the DNAME to the resolver, and the authoritative server responds positively to the A...

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...
