Descriptions
In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before 0.3.1.9, an attacker can cause a denial of service (application hang) via crafted PEM input that signifies a public key requiring a password, which triggers an attempt by the OpenSSL library to ask the user for the password, aka TROVE-2017-011.
En Tor, en versiones anteriores a la 0.2.5.16; de la versión 0.2.6 hasta la 0.2.8 anterior a la 0.2.8.17; versiones 0.2.9 anteriores a la 0.2.9.14; versiones 0.3.0 anteriores a la 0.3.0.13 y versiones 0.3.1 anteriores a la 0.3.1.9, un atacante puede provocar una denegación de servicio (bloqueo de la aplicación) mediante una entrada PEM manipulada que represente una clave pública que requiera una contraseña. Esto da lugar a que la biblioteca Open SSLE intente preguntar la contraseña al usuario. Esto también se conoce como TROVE-2017-011.
