guacamole is vulnerable to arbitrary code execution. The vulnerability exists due to a memory corruption issue occurs in guac_rdp_common_svc_handle_open_event() of guac-common-svc/guac-common-svc.c, when a large stream is sent without the CHANNEL_FLAG_FIRST flag, causing the FreeRDP stream length to be unverified before reading.
