SaferVPN before 5.0.3.3 on Windows could allow low-privileged users to create or overwrite arbitrary files, which could cause a denial of service (DoS) condition, because a symlink from %LOCALAPPDATA%\SaferVPN\Log is followed.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
