Description
FreeRDP from 2.0.0 before 3.32.0 contains a null pointer dereference vulnerability that allows malicious RDP servers to crash clients by sending out-of-lifecycle serial IRPs. Attackers can send IRP_MJ_READ or IRP_MJ_WRITE before create or after close, causing CommReadFile or CommWriteFile to dereference a null handle and terminate clients using Linux serial redirection.
