By adding files to an existing installation's directory, a local attacker could hijack accounts of other users running Erlang programs or possibly coerce a service running with \"erlsrv.exe\" to execute arbitrary code as Local System. This can occur only under specific conditions on Windows with unsafe filesystem permissions."
