CVE-2022-41877
Published: 16 November 2022
FreeRDP is a free remote desktop protocol library and clients. Affected versions of FreeRDP are 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. 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 redirection channel - command line options `/drive`, `+drives` or `+home-drive`.
