Technical ContextAI · show details
Classified as CWE-200 (Information Exposure). Affects Dtls. Pion DTLS is a Go implementation of Datagram Transport Layer Security. Pion DTLS versions v1.0.0 through v3.0.10 and 3.1.0 use random nonce generation with AES GCM ciphers, which makes it easier for remote attackers to obtain the authentication key and spoof data by leveraging the reuse of a nonce in a session and a "forbidden attack". Upgrade to v3.0.11, v3.1.1, or later.
