Description TEJ RATHI 2022-11-17 13:37:14 UTC
FreeRDP is a free remote desktop protocol library and clients. Affected versions of FreeRDP are missing input validation in `urbdrc` channel. A malicious server can trick a FreeRDP based client to crash with division by zero. This issue has been addressed in version 2.9.0. All users are advised to upgrade. Users unable to upgrade should not use the `/usb` redirection switch.
