Descriptions
An issue was discovered in Tor before 0.2.9.15, 0.3.1.x before 0.3.1.10, and 0.3.2.x before 0.3.2.10. The directory-authority protocol-list subprotocol implementation allows remote attackers to cause a denial of service (NULL pointer dereference and directory-authority crash) via a misformatted relay descriptor that is mishandled during voting.
Se ha descubierto un problema en Tor en versiones anteriores a la 0.2.9.15, versiones 0.3.1.x anteriores a la 0.3.1.10 y versiones 0.3.2.x anteriores a la 0.3.2.10. La implementación del subprotocolo directory-authority protocol-list permite que atacantes remotos provoquen una denegación de servicio (desreferencia de puntero NULL y cierre inesperado de directory-authority) mediante un descriptor de relevo con formato erróneo que se gestiona de manera incorrecta durante la votación.
