Overview

Twisted is an event-based network programming and multi-protocol integration framework.

Affected versions of this package are vulnerable to Man-in-the-Middle (MitM) via the words.protocols.jabber.xmlstream. The XMPP support did not verify certificates when used with TLS, allowing an attacker to MITM connections.
