FreeRDP is a free remote desktop protocol library and clients. Affected
versions of FreeRDP may attempt integer addition on too narrow types leads
to allocation of a buffer too small holding the data written. 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.
