CVE-2019-12573 Information

Description

A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v82 for Linux and macOS could allow an authenticated local attacker to overwrite arbitrary files. The openvpn_launcher binary is setuid root. This binary supports the –log option which accepts a path as an argument. This parameter is not sanitized which allows a local unprivileged user to overwrite arbitrary files owned by any user on the system including root. This creates a denial of service condition and possible data loss if leveraged by a malicious local user.
