Official description

FreeRDP from 2.0.0 before 3.32.0 contains a memory exhaustion vulnerability in wts_read_drdynvc_data_first that allows authenticated clients to force servers to commit large memory allocations. Attackers can send a seven-byte DATA_FIRST message on an opened DVC declaring a large 32-bit length, causing zeroed resident memory growth and server resource exhaustion.
