Descriptions
Tor before 0.3.5.10, 0.4.x before 0.4.1.9, and 0.4.2.x before 0.4.2.7 allows remote attackers to cause a Denial of Service (memory leak), aka TROVE-2020-004. This occurs in circpad_setup_machine_on_circ because a circuit-padding machine can be negotiated twice on the same circuit.
Tor versiones anteriores a 0.3.5.10, versiones 0.4.x anteriores a 0.4.1.9 y versiones 0.4.2.x anteriores a 0.4.2.7, permite a atacantes remotos causar una Denegación de servicio (pérdida de memoria), también se conoce como TROVE-2020-004. Esto ocurre en la función circpad_setup_machine_on_circ porque una máquina de circuit-padding se puede negociar dos veces en el mismo circuito.
Multiple vulnerabilities were found in Tor, the worst of which could allow remote attackers to cause a Denial of Service condition. Versions less than 0.4.2.7 are affected.
