How to fix?

Overview

Affected versions of this package are vulnerable to Improper Input Validation due to missing input length validation in drive channel. A malicious server can trick a FreeRDP based client to read out of bound data and send it back to the server.

Workaround

Users who are unable to upgrade should not use the drive redirection channel - command line options /drive, +drives or +home-drive.
