Descriptions
The auth_parse_options function in auth-options.c in sshd in OpenSSH before 5.7 provides debug messages containing authorized_keys command options, which allows remote authenticated users to obtain potentially sensitive information by reading these messages, as demonstrated by the shared user account required by Gitolite. NOTE: this can cross privilege boundaries because a user account may intentionally have no shell or filesystem access, and therefore may have no supported way to read an authorized_keys file in its own home directory.
La función auth_parse_options en auth-options.c en el demonio sshd de OpenSSH antes de v5.7 muestra mensajes de depuración que contienen opciones del comando authorized_keys, lo que permite obtener información sensible a usuarios remotos autenticados mediante la lectura de estos mensajes. El problema queda demostrado con la cuenta de usuario compartida solicitada por Gitolite. NOTA: esto puede cruzar los límites de los privilegios, porque una cuenta de usuario intencionalmente no tiene acceso a una 'shell' o al sistema de archivos, y por lo tanto no tienen forma de leer un archivo authorized_keys en su propio directorio.
