1) Security restrictions bypass (CVE-ID: CVE-2018-5764)
CWE-ID: CWE-20 - Improper input validation

The vulnerability allows a remote attacker to bypass security controls on the target system.
The weakness exists in the parse_arguments() function in 'options.c' due to insufficient validation of user-supplied input. A remote attacker can send multiple '--protect-args' values and bypass the argument-sanitization protection mechanism.
