CVE-2026-11721

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...

CVE-2026-46582

In NLnet Labs Unbound 1.6.0 up to and including 1.25.1, a replay of a wildcard rrset as another piece of data, could be briefly considered DNSSEC secure based only on the RRSIG validation and stored into cache, before later validation treats it as bogus based on NSEC validation. When the resolvin...

CVE-2026-13204 Unexpected exit in certain situations 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. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through...

CVE-2026-11721 Cache poisoning possible with label count discrepancy, RRSIG, and 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...

CVE-2026-11605 Unnecessary validation of DNSSEC signed records

The issue is a resource exhaustion vulnerability associated with DNSSEC validation. BIND always validates all RRSIG records in an answer, even if they are not strictly needed. A query to an authoritative server/zone which returns many valid but superfluous RRSIG records causes the validator to...

unbound: Unbound: Denial of Service due to excessive resource consumption with large DNS Resource Record Sets

A flaw was found in Unbound. A remote attacker can exploit this vulnerability by sending specially crafted DNS responses containing very large Resource Record Sets RRsets that require name compression. This can cause Unbound to spend a significant amount of time processing these responses, leadin...
