A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol (RDP). This use-after-free vulnerability exists in the smartcard RDPDR device handler. A remote attacker could exploit this by triggering a worker thread creation failure after device registration during channel setup. This leads to the deallocation of a device pointer while the device manager (devman) still retains a reference, which can result in a denial of service (crash) or potentially lead to arbitrary code execution.
