## Description

FreeRDP is a free remote desktop protocol library and clients. FreeRDP
based clients on unix systems using `/parallel` command line switch might
read uninitialized data and send it to the server the client is currently
connected to. FreeRDP based server implementations are not affected. Please
upgrade to 2.8.1 where this issue is patched. If unable to upgrade, do not
use parallel port redirection (`/parallel` command line switch) as a
workaround.
