Security Bulletin: IBM i is affected by BIND being too lenient accepting records with forged data and consuming excessive CPU when a resolver is performing DNSSEC validation [CVE-2025-40778, CVE-2026-1519].
Summary Domain Name System for IBM i is vulnerable to BIND being too lenient when accepting records from answers allowing an attack to inject forged data into cache CVE-2025-40778, and consuming excessive CPU when a resolver is performing DNSSEC validation and encounters a maliciously crafted zon...
NSEC3 closest-encloser proof validation enters unbounded loop on cross-zone responses
The NSEC3 closest-encloser proof validation in hickory-proto's DnssecDnsHandle walks from the QNAME up to the SOA owner name, building a list of candidate encloser names. The iterator used assumes the QNAME is a descendant of the SOA owner, terminating only when the current candidate equals the S...
