A malicious gateway might allow\nclient memory to be written out of bounds. This issue has been resolved in\nversion 2.4.1. If you are unable to update then use `/gt:http` rather than\n/gt:rdp connections if possible or use a direct connection without a\ngateway. (CVE-2021-41159)\n\nIn affected versions a malicious server might trigger out of bound writes\nin a connected client. Connections using GDI or SurfaceCommands to send\ngraphics updates to the client might send `0` width/height or out of bound\nrectangles to trigger out of bound writes. With `0` width or heigth the\nmemory allocation will be `0` but the missing bounds checks allow writing\nto the pointer at this (not allocated) region. This issue has been patched\nin FreeRDP 2.4.1.
