CVE-ID: CVE-2017-1000367

CWE-ID: CWE-77 - Improper Neutralization of Special Elements used in a Command ('Command Injection')

Description

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to command validation flaw in the get_process_ttyname() function. A local attacker can issue a specially crafted sudo command, cause the system to recognize the user's tty as an arbitrary file and overwrite arbitrary files. Exploitation of the bug is possible in case a malicious user has sudo privileges, the system contains SELinux and sudo has been built on SELinux support.

Successful exploitation of the vulnerability results in root access to the system.
