CVE-2024-1300 Information

Description

A vulnerability in the Eclipse Vert.x toolkit causes a memory leak in TCP servers configured with TLS and SNI support. When processing an unknown SNI server name assigned the default certificate instead of a mapped certificate the SSL context is erroneously cached in the server name map leading to memory exhaustion. This flaw allows attackers to send TLS client hello messages with fake server names triggering a JVM out-of-memory error.
