OESA-2026-3184 coredns security update

CoreDNS is a fast and flexible DNS server. The key word here is flexible: with CoreDNS you are able to do what you want with your DNS data by utilizing plugins. Security Fixes: CoreDNS is a DNS server that chains plugins. Prior to version 1.14.2, a denial of service vulnerability exists in...

Uncaught Exception

Overview Affected versions of this package are vulnerable to Uncaught Exception in the transfer. An attacker can cause a panic and disrupt DNS service availability by sending an AXFR request to a zone configured with k8sexternal headless-service zone transfers when a headless service endpoint...

NULL Pointer Dereference

Overview Affected versions of this package are vulnerable to NULL Pointer Dereference via the proxyproto plugin when handling a PROXY v2 datagram with a non-UDP transport. An attacker can cause the process to crash by sending a specially crafted 28-byte UDP packet when the plugin is enabled...

CVE-2026-62994

CoreDNS is a DNS server written in Go. From 1.9.4 until 1.14.5, a network DNS client allowed to request AXFR for a CoreDNS zone can trigger a panic when CoreDNS is configured with k8sexternal headless-service zone transfers and Kubernetes contains a headless service endpoint with no declared port...

CVE-2026-62299

CoreDNS (rewrite plugin, edns0.go) prior to version 1.14.5 could panic when a downstream plugin returns a response with no OPT record. The code path in edns0.go dereferenced a DNS OPT without a nil check, triggered by a query matching a rewrite edns0 rule (local/nsid/subnet with set/append/replac...

CoreDNS (Go) vulnerability CVE-2026-62309 affects the proxyproto plugin. A crafted PROXY v2 header with a non-UDP transport (family 0x11) can cause a crash via PacketConn.ReadFrom, where a nil readFrom result is reinterpreted after a failed parse and addr.String() is logged before crash recovery....
