How to fix?

Upgrade tor to version 0.2.2.34 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure. Tor before 0.2.2.34, when configured as a bridge, uses direct DirPort access instead of a Tor TLS connection for a directory fetch, which makes it easier for remote attackers to enumerate bridges by observing DirPort connections.
