Description

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

Solution(s)

  • huawei-euleros-2_0_sp8-upgrade-freerdp
  • huawei-euleros-2_0_sp8-upgrade-freerdp-libs
  • huawei-euleros-2_0_sp8-upgrade-libwinpr
