Description
FreeRDP versions from 3.0.0 before 3.32.0 contain a null pointer dereference in the rdpsnd channel when a fragment sets CHANNEL_FLAG_LAST without CHANNEL_FLAG_FIRST. A malicious RDP server can send a malformed rdpsnd PDU on a fresh channel to crash the client and cause denial of service.
