CVE-2026-62309

A flaw was found in CoreDNS. A remote attacker can send a specially crafted 28-byte UDP datagram to a CoreDNS server with the proxyproto plugin enabled. This malformed datagram can cause the CoreDNS process to crash, leading to a denial of service DoS. The vulnerability arises from improper...

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-2026-62309 CoreDNS: proxyproto plugin panics on PPv2 datagram with non-UDP transport — single 28-byte packet remote DoS

CoreDNS is a DNS server written in Go. Prior to 1.14.4, a single 28-byte UDP datagram can crash the CoreDNS process when the proxyproto plugin is enabled because plugin/pkg/proxyproto/proxyproto.go PacketConn.ReadFrom handles a PROXY v2 header with non-UDP transport such as family byte 0x11,...

GO-2022-0233 Resource exhaustion in github.com/pires/go-proxyproto

The PROXY protocol server does not impose a timeout on reading the header from new connections, allowing a malicious client to cause resource exhaustion and a denial of service by opening many connections and sending no data on them. v0.6.0 of the proxyproto package adds support for a user-define...

Go-proxyproto DoS

The vulnerability of the PROXY protocol library in the Golang language is related to the absence of a timeout during the waiting for the proxy protocol header. Exploiting this vulnerability allows a remote attacker to cause service interruptions...
