The connection_edge_process_relay_cell function in or/relay.c in Tor before 0.2.3.25 maintains circuits even if an unexpected SENDME cell arrives, which might allow remote attackers to cause a denial of service (memory consumption or excessive cell reception rate) or bypass intended flow-control restrictions via a RELAY_COMMAND_SENDME command. La función connection_edge_process_relay_cell en o/relay.c en Tor antes de v0.2.3.25 mantiene circuitos incluso si llega una célula SendMe llega, lo que podría permitir a atacantes remotos provocar una denegación de servicio (consumo de memoria o la velocidad excesiva de células recepción) o evitar las restricciones de control de flujo a través de un comando RELAY_COMMAND_SENDME. • http://openwall.com/lists/oss-security/2012/11/26/11 http://secunia.com/advisories/51329 http://security.gentoo.org/glsa/glsa-201301-03.xml https://bugs.gentoo.org/show_bug.cgi?id=444804 https://bugzilla.redhat.com/show_bug.cgi?id=880310 https://exchange.xforce.ibmcloud.com/vulnerabilities/80289 https://gitweb.torproject.org/arma/tor.git/commitdiff/b9b54568c0bb64c32bd0b362954bdbc8c1234b16 https://gitweb.torproject.org/tor.git/blob/release-0.2.3:/ReleaseNotes https://trac.torproject.org&# • CWE-399: Resource Management Errors •

The tor_timegm function in common/util.c in Tor before 0.2.2.39, and 0.2.3.x before 0.2.3.22-rc, does not properly validate time values, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a malformed directory object, a different vulnerability than CVE-2012-4419. La función tor_timegm en común/util.c en Tor v0.2.2.39 antes, y antes de v0.2.3.x v0.2.3.22-rc, no valida correctamente los valores de tiempo, lo que permite a atacantes remotos provocar una denegación de servicio (error de aserción y salida del demonio) a través de una lista de objetos con formato incorrecto. Se trata de una vulnerabilidad diferente a CVE-2012-4419a. • http://lists.fedoraproject.org/pipermail/package-announce/2012-September/088006.html http://lists.opensuse.org/opensuse-updates/2012-10/msg00005.html http://openwall.com/lists/oss-security/2012/09/12/5 http://security.gentoo.org/glsa/glsa-201301-03.xml https://gitweb.torproject.org/tor.git/blob/release-0.2.2:/ReleaseNotes https://gitweb.torproject.org/tor.git/commit/973c18bf0e84d14d8006a9ae97fde7f7fb97e404 https://lists.torproject.org/pipermail/tor-talk/2012-September/025501.html https://trac. • CWE-20: Improper Input Validation •

The compare_tor_addr_to_addr_policy function in or/policies.c in Tor before 0.2.2.39, and 0.2.3.x before 0.2.3.21-rc, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a zero-valued port field that is not properly handled during policy comparison. La función compare_tor_addr_to_addr_policy en or/policies.c en Tor antes de v0.2.2.39 y v0.2.3.x antes de v0.2.3.21-rc, permite a atacantes remotos provocar una denegación de servicio (error de aserción y salida del demonio) a través de un valor cero en el campo port (puerto) que no se gestionado correctamente durante la comparación de políticas. • http://lists.fedoraproject.org/pipermail/package-announce/2012-September/088006.html http://lists.opensuse.org/opensuse-updates/2012-10/msg00005.html http://openwall.com/lists/oss-security/2012/09/13/2 http://secunia.com/advisories/50583 http://security.gentoo.org/glsa/glsa-201301-03.xml https://gitweb.torproject.org/tor.git/blob/release-0.2.2:/ReleaseNotes https://gitweb.torproject.org/tor.git/commit/62d96284f7e0f81c40d5df7e53dd7b4dfe7e56a5 https://lists.torproject.org/pipermail/tor-talk/2012 •
