Technical details
The DTLS ClientHello parser validates the ciphersuite-list length against the total record length rather than remaining bytes, allowing an unauthenticated peer to trigger an out-of-bounds source read via a manipulated session_id length field. The leaked memory is echoed verbatim into the ServerHello response, disclosing adjacent process memory over the network. The vulnerability can also crash the server on the first malicious packet.
