An out-of-bounds read vulnerability was discovered in FreeRDP due to improper input length validation in the drive channel. A malicious server can trick a FreeRDP based client to read out-of-bound data and send it back to the server.

Mitigation

Do not use the drive redirection channel - command line options /drive, +drives or +home-drive.
