CVE-2026-69186

c-ares , an asynchronous DNS resolver library, is affected by a memory-amplification denial of service in ares_dns_parse(). Prior to 1.34.7 , the function trusts attacker-controlled ANCOUNT, NSCOUNT, and ARCOUNT header fields without first confirming the response contains enough bytes for the cla...

CVE-2026-69186 c-ares: Memory-amplification denial of service via unvalidated DNS header record counts

c-ares is an asynchronous resolver library. Prior to 1.34.7, aresdnsparse trusts the attacker-controlled ANCOUNT, NSCOUNT, and ARCOUNT fields before confirming that the DNS response contains enough bytes for the claimed records. Because processanswer invokes parsing before transaction ID and...

GHSA-9GM5-9RFH-M6VX CoreDNS DoH/DoQ/gRPC bypass UPDATE rejection enforced on UDP/TCP

Summary CoreDNS accepted RFC 2136 UPDATE messages over DoH, DoH3, DoQ, and DNS-over-gRPC, then allowed the proxy/forward plugin to send them unchanged to an upstream DNS server. UDP, TCP, and DoT rejected the same opcode before plugin dispatch. If an update-capable upstream trusts CoreDNS's sourc...

CVE-2026-86003

A flaw was found in CoreDNS. The DNS-over-HTTPS, DNS-over-HTTP/3, DNS-over-QUIC, and DNS-over-gRPC listeners do not properly validate incoming DNS update requests. An unauthenticated client can send a specially crafted DNS update RFC 2136 UPDATE that CoreDNS forwards to an upstream DNS server. If...

CVE-2026-86003 CoreDNS DoH/DoQ/gRPC bypass UPDATE rejection enforced on UDP/TCP
