nodejs: Nodejs denial of service

A flaw in Node.js TLS error handling allows remote attackers to crash or exhaust resources of a TLS server when pskCallback or ALPNCallback are in use. Synchronous exceptions thrown during these callbacks bypass standard TLS error handling paths tlsClientError and error, causing either immediate...

crypto/tls: go crypto/tls ALPN negotiation error contains attacker controlled information

The crypto/tls conn.Handshake method returns an error on the server-side when ALPN negotation fails which can contain arbitrary attacker controlled information provided by the client-side of the connection which is not escaped. This affects programs which log these errors without any additional...

CVE-2026-3547

CVE-2026-3547 concerns wolfSSL before or including version 5.8.4, where an out-of-bounds read can occur in ALPN parsing due to incomplete validation when ALPN is enabled (HAVE_ALPN / --enable-alpn). A crafted ALPN protocol list may trigger a crash, causing a denial of service. ALPN is disabled by...

Why Most DDoS Protection Fails: Solving for Continuity and Resilience

Most organisations assume DDoS Distributed denial of service protection is a box they’ve already ticked. If traffic spikes or an attack starts, the thinking goes, their provider will absorb it and move on. But in the real world it can be a different story. Many incidents aren’t caused by the scal...
