02 Feb 2020 — The daemon in Tor through 0.4.1.8 and 0.4.2.x through 0.4.2.6 does not verify that a rendezvous node is known before attempting to connect to it, which might make it easier for remote attackers to discover circuit information. NOTE: The network team of Tor claims this is an intended behavior and not a vulnerability ** EN DISPUTA ** El demonio en Tor hasta la versión 0.4.1.8 y versiones 0.4.2.x hasta la versión 0.4.2.6, no comprueba que un nodo rendezvous sea conocido antes de intentar conectarse a él, lo qu... • https://lists.torproject.org/pipermail/tor-dev/2020-February/014146.html •
