Security readout for executives and security teams
CVE-2002-0391 is a critical flaw in SunRPC-derived code used by some Unix/Linux RPC services. A remote, unauthenticated attacker could trigger memory corruption and potentially run code by sending oversized RPC data. Business risk is highest for legacy systems exposing RPC services such as rpc.cmsd or dmispd. Likely exposure is legacy Unix/Linux or related systems running affected SunRPC-derived libraries and reachable RPC services. The source bundle names libc, glibc, dietlibc, rpc.cmsd, and dmispd, but does not provide a complete affected-product list. Treat as high-priority for legacy infrastructure and any internet-reachable RPC services. The vulnerability is old, but the impact is critical where affected systems remain exposed or unsupported. Mitigation focus: Apply relevant vendor security updates for affected operating systems and libraries.; Disable unnecessary RPC services, especially legacy services named in advisories.; Restrict RPC service exposure to trusted networks only..
