TencentOS Server 4: etcd (TSSA-2026:0852)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:0852 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:...

etcd: `tlsListener.acceptLoop` spawns unbounded handshake goroutines with no deadline

AZL-95946 CVE-2026-73500 affecting package prometheus-adapter for versions less than 0.12.0-9

etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.5.33, 3.6.14, and 3.7.1, a network attacker who can reach an etcd TLS listener can open many TCP connections and never send a ClientHello. In client/pkg/transport/listenertls.go, each connection handle...

CVE-2026-52879 Klever-Go: Unbounded goroutine spawn on direct-message ingress enables peer-driven DoS

Klever-Go is the Go implementation of the Klever blockchain protocol. In versions 1.7.14 through 1.7.17, the direct-message ingress handler spawns a new goroutine for every incoming direct message before the processor-level antiflood layer makes any admission decision, with no semaphore, throttle...

GHSA-6VCH-Q96H-7GC3 etcd: `tlsListener.acceptLoop` spawns unbounded handshake goroutines with no deadline

Impact What kind of vulnerability is it? Who is impacted? A network attacker who can reach an etcd TLS listener can open many TCP connections and never send a ClientHello. Each connection spawns a goroutine in the etcd server process that blocks indefinitely inside tls.Conn.Handshake, and each is...

etcd: etcd: Denial of Service via unbounded TLS handshake goroutines

A flaw was found in etcd, a distributed key-value store. A remote attacker can exploit this by opening numerous TCP connections to an etcd TLS listener without completing the TLS handshake. This action causes the tlsListener.acceptLoop to spawn an unbounded number of goroutines, which consume...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the lack of timeout configuration in the http.DefaultClient used for remote post-serve actions. An attacker can exhaust system memory and crash the process by registering a...

GHSA-HF2G-6J7H-98WG klever-go: Unbounded goroutine spawn on direct-message ingress enables peer-driven DoS

Summary networkMessenger.directMessageHandler in network/p2p/libp2p/netMessenger.go spawns a fresh goroutine for every incoming direct message before the antiflood layer makes an admission decision. There is no semaphore, throttler, or bound on concurrent in-flight spawns. A single connected libp...

CVE-2026-32934

CoreDNS is a DNS server that chains plugins. In versions prior to 1.14.3, the DNS-over-QUIC DoQ server can be driven into unbounded goroutine and memory growth by a remote client that opens many QUIC streams and sends only 1 byte per stream. When the worker pool is full, CoreDNS still spawns a...

CVE-2026-32934

CoreDNS prior to version 1.14.3 is vulnerable: the DNS-over-QUIC (DoQ) server can spawn unbounded goroutines/memory growth when a remote client opens many QUIC streams and sends 1 byte per stream. With a full worker pool, CoreDNS still creates a goroutine per stream to wait for a worker token, an...

PT-2026-37094

Name of the Vulnerable Software and Affected Versions CoreDNS versions prior to 1.14.3 Description The DNS-over-QUIC DoQ server can be forced into unbounded goroutine and memory growth by a remote unauthenticated client. This occurs when a client opens numerous QUIC streams and sends only one byt...

CVE-2025-47950

CoreDNS is a DNS server that chains plugins. In versions prior to 1.12.2, a Denial of Service DoS vulnerability exists in the CoreDNS DNS-over-QUIC DoQ server implementation. The server previously created a new goroutine for every incoming QUIC stream without imposing any limits on the number of...
