Tor before 0.2.2.34, when configured as a client or bridge, sends a TLS certificate chain as part of an outgoing OR connection, which allows remote relays to bypass intended anonymity properties by reading this chain and then determining the set of entry guards that the client or bridge had selected. Tor, antes de v0.2.2.34, cuando se configura como cliente o bridge, envía una cadena de certificado TLS como parte de una conexión saliente OR, lo que permite a relays remotos evitar la anonimidad intencionada cuando se determina un conjunto de guardas de entrada seleccionadas por el cliente o bridge. • http://www.debian.org/security/2011/dsa-2331 https://blog.torproject.org/blog/tor-02234-released-security-patches • CWE-264: Permissions, Privileges, and Access Controls •

Buffer overflow in the policy_summarize function in or/policies.c in Tor before 0.2.1.30 allows remote attackers to cause a denial of service (directory authority crash) via a crafted policy that triggers creation of a long port list. Desbordamiento de búfer en la función policy_summarize en or/policies.c en Tor antes de v0.2.1.30 permite a atacantes remotos causar una denegación de servicio (caída de la autoridad de directorio) a través de una política manipulada que provoca la creación de una lista de puertos largos. • http://lists.fedoraproject.org/pipermail/package-announce/2011-June/061258.html http://secunia.com/advisories/43548 http://secunia.com/advisories/44862 http://www.securityfocus.com/bid/46618 https://bugzilla.redhat.com/show_bug.cgi?id=705192 https://bugzilla.redhat.com/show_bug.cgi?id=705194 https://gitweb.torproject.org/tor.git/commit/43414eb98821d3b5c6c65181d7545ce938f82c8e https://lists.torproject.org/pipermail/tor-announce/2011-February/000000.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha makes calls to Libevent within Libevent log handlers, which might allow remote attackers to cause a denial of service (daemon crash) via vectors that trigger certain log messages. Tor antes de v0.2.1.29 y v0.2.2.x antes de v0.2.2.21-alfa realiza llamadas a libevent dentro de manejadores de log de libevent, que podría permitir a atacantes remotos provocar una denegación de servicio (por caída del demonio) a través de vectores que lanzan ciertos mensajes de log. • http://archives.seul.org/or/announce/Jan-2011/msg00000.html http://blog.torproject.org/blog/tor-02129-released-security-patches http://www.securityfocus.com/bid/45953 https://exchange.xforce.ibmcloud.com/vulnerabilities/64889 https://gitweb.torproject.org/tor.git/blob/refs/heads/release-0.2.2:/ChangeLog https://trac.torproject.org/projects/tor/ticket/2190 •

Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha does not properly manage key data in memory, which might allow local users to obtain sensitive information by leveraging the ability to read memory that was previously used by a different process. Tor en versiones anteriores a la 0.2.1.29 y 0.2.2.x anteriores a la 0.2.2.21-alpha no gestiona apropiadamente datos de clave en memoria, lo que puede permitir a usuarios locales obtener información confidencial a través de la lectura de memoria que ha sido utilizada previamente por un proceso diferente. • http://archives.seul.org/or/announce/Jan-2011/msg00000.html http://blog.torproject.org/blog/tor-02129-released-security-patches http://secunia.com/advisories/42905 http://secunia.com/advisories/42907 http://www.debian.org/security/2011/dsa-2148 http://www.openwall.com/lists/oss-security/2011/01/18/7 http://www.securityfocus.com/bid/45832 http://www.securitytracker.com/id?1024980 http://www.vupen.com/english/advisories/2011/0131 http://www.vupen.com/english/advisories/ • CWE-399: Resource Management Errors •

Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha does not properly check the amount of compression in zlib-compressed data, which allows remote attackers to cause a denial of service via a large compression factor.
