FreeRDP is a free remote desktop protocol library and clients. Affected
versions of FreeRDP are missing path canonicalization and base path check
for drive channel. A malicious server can trick a FreeRDP based client to
read files outside the shared directory. 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 /drive, /drives or +home-drive redirection switch.
