Hi,

The following vulnerabilities were published for snowflake, via the
github.com/pion/dtls/v2 package included into debian/vendor/

CVE-2022-29189[0]:
| Pion DTLS is a Go implementation of Datagram Transport Layer Security.
| Prior to version 2.1.4, a buffer that was used for inbound network
| traffic had no upper limit. Pion DTLS would buffer all network traffic
| from the remote user until the handshake completes or timed out. An
| attacker could exploit this to cause excessive memory usage. Version
| 2.1.4 contains a patch for this issue. There are currently no known
| workarounds available.

| Prior to version 2.1.4, an attacker can send packets that sends Pion
| DTLS into an infinite loop when processing. Version 2.1.4 contains a
| patch for this issue. There are currently no known workarounds
| available.
