freerdp: FreeRDP: Arbitrary code execution via crafted Remote Desktop Protocol (RDP) server messages

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. The gdisurfacebits function, which processes SURFACEBITSCOMMAND messages, does not properly validate image dimensions bmp.width and bmp.height provided by a malicious RDP server. This can lead to a heap buffer...
