Description
### Impact When a special crafted packet is received via SslHandler it doesn't correctly handle validation of such a packet in all cases which can lead to a native crash. ### Workarounds As workaround its possible to either disable the usage of the native SSLEngine or changing the code from: ``` SslContext context = ...; SslHandler handler = context.newHandler(....); ``` to: ``` SslContext context = ...; SSLEngine engine = context.newEngine(....); SslHandler handler = new SslHandler(engine, ....); ```
