Background
Pion DTLS is a Go library that provides Datagram Transport Layer Security (DTLS) functionality. It is used for securing communication channels in applications that require reliable and encrypted data transfer. Pion DTLS is vulnerable to an issue where an attacker can send packets that will send the library into an infinite loop during processing.
