eclipse-vertx/vert.x: eclipse-vertx/vert.x: Denial of Service via TLS handshake with wildcard server name

A flaw was found in eclipse-vertx/vert.x. A remote attacker can exploit this vulnerability by performing a Transport Layer Security TLS handshake and presenting a server name extension with a server wildcard name. This can lead to a denial of service DoS condition, impacting the availability of t...
