FreeRDP is a free remote desktop protocol library and clients. Affected versions of FreeRDP are missing input length validation in the urbdrc channel. A malicious server can trick a FreeRDP based client to read out of bound data and send it back to the server. This issue has been addressed in version 2.9.0 and all users are advised to upgrade. Users unable to upgrade should not use the /usb redirection switch.
