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...

When Handshakes Tell the Truth: Detecting Web Bad Bots Via TLS Fingerprints

Automated traffic continued to surpass human-generated traffic on the web, and a rising proportion of this automation was explicitly malicious. Evasive bots could pretend to be real users, even solve Captchas and mimic human interaction patterns. This work explores a less intrusive, protocol-leve...

📄 crypto/x509 TLS Certificate Parsing

This Go program demonstrates a theoretical denial of service risk associated with handling unusually large X.509 certificates in TLS connections. It programmatically generates a self-signed certificate containing a very large number of Subject Alternative Names SANs and configures an HTTP client ...

CVE-2026-1584

A flaw was found in gnutls. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted ClientHello message with an invalid Pre-Shared Key PSK binder value during the TLS handshake. This can lead to a NULL pointer dereference, causing the server to crash and...

GnuTLS 安全漏洞

GnuTLS is an open-source, free security communication library developed by GnuTLS that enables the implementation of SSL, TLS, and DTLS protocols. There is a security vulnerability in gnutls. This vulnerability stems from the possibility of remote, unverified attackers sending specially crafted...

CVE-2025-61730

During the TLS 1.3 handshake if multiple messages are sent in records that span encryption level boundaries for instance the Client Hello and Encrypted Extensions messages, the subsequent messages may be processed before the encryption level changes. This can cause some minor information disclosu...
