| Doc Text: |
A flaw was found in FreeRDP. A malicious Remote Desktop Protocol (RDP) server can cause a Denial of Service (DoS) by crashing the proxy service during session termination. When the dynamic channel dump module is enabled, transmitting dynamic channel data while a client disconnects triggers a multi-thread synchronization flaw where released memory is accessed, causing the proxy process to terminate.
