Descriptions
Todd Miller's sudo version 1.8.20p1 and earlier is vulnerable to an input validation (embedded newlines) in the get_process_ttyname() function resulting in information disclosure and command execution.
La versión 1.8.20p1 y anteriores de sudo de Todd Miller es vulnerable a una validación de entradas (nuevas líneas embebidas) en la función get_process_ttyname() que da lugar a una revelación de información y la ejecución de comandos.
It was found that the original fix for CVE-2017-1000367 was incomplete. A flaw was found in the way sudo parsed tty information from the process status file in the proc filesystem. A local user with privileges to execute commands via sudo could use this flaw to escalate their privileges to root.
