Fix CVE-2022-21716: Twisted is an event-based framework for internet
applications, supporting Python 3.6+. Prior to 22.2.0, Twisted SSH
client and server implement is able to accept an infinite amount of data
for the peer's SSH version identifier. This ends up with a buffer using
all the available memory. The attach is a simple as `nc -rv localhost 22
< /dev/zero`. A patch is available in version 22.2.0. There are
currently no known workarounds.
