04 Nov 2017 — Tor Browser before 7.0.9 on macOS and Linux allows remote attackers to bypass the intended anonymity feature and discover a client IP address via vectors involving a crafted web site that leverages file:// mishandling in Firefox, aka TorMoil.

23 Jul 2017 — debian/tor.init in the Debian tor_0.2.9.11-1~deb9u1 package for Tor was designed to execute aa-exec from the standard system pathname if the apparmor package is installed, but implements this incorrectly (with a wrong assumption that the specific pathname would remain the same forever), which allows attackers to bypass intended AppArmor restrictions by leveraging the silent loss of this protection mechanism.

02 Jul 2017 — Tor 0.3.x before 0.3.0.9 has a guard-selection algorithm that only considers the exit relay (not the exit relay's family), which might allow remote attackers to defeat intended anonymity properties by leveraging the existence of large families. Las versiones 0.3.x de Tor anteriores a la 0.3.0.9 cuentan con un algoritmo de selección de restricciones que solo considera el exit relay (no la familia del exit relay), lo que podría permitir que atacantes remotos superen las propiedades de anonimato planeadas apro... • https://blog.torproject.org/blog/tor-0309-released-security-update-clients • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

24 Dec 2016 — Tor before 0.2.8.9 and 0.2.9.x before 0.2.9.4-alpha had internal functions that were entitled to expect that buf_t data had NUL termination, but the implementation of or/buffers.c did not ensure that NUL termination was present, which allows remote attackers to cause a denial of service (client, hidden service, relay, or authority crash) via crafted data.
