FreeRDP is a free implementation of the Remote Desktop Protocol (RDP),
released under the Apache license. In affected versions a malicious server
might trigger out of bound writes in a connected client. Connections using
GDI or SurfaceCommands to send graphics updates to the client might send
0 width/height or out of bound rectangles to trigger out of bound writes.
With 0 width or heigth the memory allocation will be 0 but the missing
bounds checks allow writing to the pointer at this (not allocated) region.
This issue has been patched in FreeRDP 2.4.1.
