CVSS 5.900000095367432 MEDIUM
A flaw was found in FreeRDP. A remote attacker, specifically a malicious TS Gateway, can exploit a heap-buffer-overflow vulnerability by sending a specially crafted Remote Desktop Protocol (RDP) response. This occurs because the client incorrectly uses a smaller `alloc_hint` value instead of the actual `StubLength` for buffer capacity during response reassembly. This allows attacker-controlled data to be written beyond the intended buffer, leading to a client crash and potentially enabling arbitrary code execution.
