### Summary A connection created with throws an uncaught from when it receives a record of another content type while waiting for the rest of a handshake message that was split across records. A peer can trigger this with 18 bytes before the handshake, without authentication, which terminates Node.js processes that use the documented socket wiring. Fixed in node-forge 1.4.1. ### Details In , handles a record that arrives while a handshake message split across records is incomplete. If the record has any other content type (change_cipher_spec, alert, application_data or heartbeat), forge correctly reports "Invalid fragmented record." through with a fatal alert. That fatal error closes and resets the connection, which sets to . then continues with and throws out of . The code is unchanged since the first release. RFC 5246 section 6.2.1 allows a handshake message to be fragmented across records, and RFC 8446 section 5.1 forbids interleaving handshake messages with other record types. Failing the connection with is the intended behavior; the bug is the crash after the error. node-forge reports TLS protocol errors through the callback, so applications do not normally wrap in / . When is called from a Node.js socket handler, as in the documented usage, the exception is uncaught and terminates the process. The fix returns from right after the fatal error. The connection is failed, the alert is sent and the callback is called as before, and no longer throws. ### Patches Fixed in node-forge 1.4.1. The connection still fails with a fatal alert and the callback, but no longer throws. ### Workarounds Wrap every call to in / . The connection has already been failed and closed when the exception is thrown, so the exception can be ignored or the socket destroyed. ### Proof of concept Input (server mode), two records, 18 bytes: 16 03 01 00 06 01 00 00 10 03 01 handshake record: ClientHello header announcing 16 bytes, 2 present 15 03 01 00 02 02 28 alert record // c = forge.tls.crea
