  "details" : [ "In Eclipse Californium version 2.3.0 to 2.6.0, the certificate based (x509 and RPK) DTLS handshakes accidentally fails, because the DTLS server side sticks to a wrong internal state. That wrong internal state is set by a previous certificate based DTLS handshake failure with TLS parameter mismatch. The DTLS server side must be restarted to recover this. This allow clients to force a DoS.", "A flaw was found in californium. The certificate based (x509 and RPK) DTLS handshakes fails due to the DTLS server side being set to a wrong internal state by a previous certificate based DTLS handshake failure with TLS parameter mismatch. The highest threat from this vulnerability is to system availability." ],
