  "details": "The TLS 1.3 Certificate-message parser in NetX Secure decrements the message length to skip a context byte without first establishing that the message has a byte to skip. A zero-length Certificate message therefore wraps the unsigned length to `0xFFFFFFFF`, which makes the bounds check that follows vacuous and sends the parser reading past the session packet buffer.\n\n\n\nThe trigger is a four-byte handshake header and requires no cryptographic validity. It is reachable pre-authentication.",
