Multiple heap-based buffer overflows in Tor before 0.2.2.35 allow remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code by (1) establishing a SOCKS connection to SocksPort or (2) leveraging a SOCKS proxy configuration. Múltiples desbordamientos de buffer de memoria dinámica en versiones anteriores a v0.2.2.35 de Tor que permite a atacantes remotos causar una denegación de servicio (corrupción de memoria) o una posible ejecución de código de su elección mediante (1) el establecimiento de una conexión STOKS a un puerto SocksPort o (2) aprovechando una configuración de proxy STOKS. • http://www.debian.org/security/2011/dsa-2363 https://blog.torproject.org/blog/tor-02235-released-security-patches • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Tor before 0.2.2.34, when configured as a bridge, accepts the CREATE and CREATE_FAST values in the Command field of a cell within an OR connection that it initiated, which allows remote relays to enumerate bridges by using these values. Tor antes de v0.2.2.34, cuando se configura como bridge, acepta los valores CREATE y CREATE_FAST en el campo Command de una conexión OR que inicializa, lo que permite a relays remotos enumerar bridges usando esos valores. • http://www.debian.org/security/2011/dsa-2331 https://blog.torproject.org/blog/tor-02234-released-security-patches • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2011-2768
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 •
