Summary

A flaw was found in Netty's `netty-handler-ssl-ocsp` component. A remote attacker can exploit this vulnerability by providing an Online Certificate Status Protocol (OCSP) response that omits the optional `nextUpdate` field. This omission causes the OCSP validation to be silently skipped, leading to applications proceeding with an unvalidated certificate. This can result in a bypass of security controls where certificate validation is expected.
