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...

gnutls: gnutls: Remote Denial of Service via crafted ClientHello with invalid PSK binder

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...
