Descriptions

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.

Las versiones de Tor anteriores a v0.2.2.34, cuando son configuradas en modo puente, utilizan el acceso directo a DirPort en vez de una conexión TLS a Tor para un directorio localizado, lo cual puede provocar que un atacante remoto pueda obtener una lista de los puentes por medio de la observación de las conexiones a través del puerto DirPort.
