If you cannot patch yet, restricting access to the ggml-rpc server or implementing input validation to limit message sizes may reduce exposure.
Description
An uncaught exception vulnerability exists in llama.cpp versions from b2877 up to but not including b11935 in the ggml-rpc server. This flaw allows unauthenticated remote attackers to crash the rpc-server by sending oversized message lengths after the HELLO handshake, causing a denial of service.
