In FreeRDP less than or equal to 2.1.2, an integer overflow exists due to
missing input sanitation in rdpegfx channel. All FreeRDP clients are
affected. The input rectangles from the server are not checked against
local surface coordinates and blindly accepted. A malicious server can send
data that will crash the client later on (invalid length arguments to a
memcpy) This has been fixed in 2.2.0. As a workaround, stop using command
line arguments /gfx, /gfx-h264 and /network:auto

| mdeslaur | The freerdp package in Ubuntu 16.04 LTS and Ubuntu 18.04 LTS does not build a server library. This is simply a client denial of service that has a negligible security impact. |
