What is CVE-2024-34363?

A vulnerability exists within Envoy, a widely-used cloud-native edge and service proxy, which arises from the interactions with the nlohmann JSON library. When incomplete UTF-8 strings are serialized, this can lead to the library throwing an uncaught exception. The consequence of such an exception is a crash of the Envoy process, potentially interrupting service and affecting applications that rely on its functionality. This vulnerability underlines the importance of robust error handling in software reliant on third-party libraries.
