Denial Of Service (DoS)

github.com/coredns/coredns is vulnerable to Denial of Service DoS. The vulnerability is due to lack of limits on concurrent QUIC streams and goroutines per connection, allowing an attacker to exhaust memory by opening many streams simultaneously...

The vulnerability of the QUIC protocol and CoreDNS server implementation allows a attacker to cause a service failure.

The vulnerability of the QUIC protocol and CoreDNS server lies in the unlimited distribution of resources. Exploiting this vulnerability could allow a malicious actor to cause service failures due to insufficient available RAM...

CVE-2025-47950

A memory exhaustion vulnerability was found in CoreDNS when operating with QUIC traffic streams. The CoreDNS server in affected versions would spawn a new goroutine for each incoming QUIC stream without limit. This flaw allows a malicious user to create an unbounded number of QUIC streams and...

CoreDNS Vulnerable to DoQ Memory Exhaustion via Stream Amplification

Summary A Denial of Service DoS vulnerability was discovered in the CoreDNS DNS-over-QUIC DoQ server implementation.
