Doc Text:
A flaw was found in FreeRDP. A malicious or compromised Remote Desktop Protocol (RDP) server can trigger a Denial of Service (DoS) by sending crafted mapped video geometry updates to a connecting client with video redirection enabled. Due to an integer overflow during coordinate calculations, the client triggers an internal error assertion and terminates unexpectedly.
