This indicates an attempt to exploit one of three vulnerabilities in Trend Micro ServerProtect for Windows.
These vulnerabilities are caused by boundary check errors in "RPCFN_CMON_SetSvcImpersonateUser", "RPCFN_ENG_NewManualScan" and "RPCFN_SetComputerName" in StRpcSrv.dll. A remote attacker may exploit this to execute arbitrary code.
