Description
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to improper input validation in the get_process_ttyname() function when parsing tty information from the process status file in the proc files by sudo. A local attacker can supply a specially crafted file to obtain potentially sensitive information or execute arbitrary command with root privileges.
Successful exploitation of the vulnerability may result in system compromise.
