https://notcve.org/view.php?id=CVE-2021-41159
21 Oct 2021 — FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. All FreeRDP clients prior to version 2.4.1 using gateway connections (`/gt:rpc`) fail to validate input data. A malicious gateway might allow client memory to be written out of bounds. This issue has been resolved in version 2.4.1. If you are unable to update then use `/gt:http` rather than /gt:rdp connections if possible or use a direct connection without a gateway. • https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-vh34-m9h7-95xq • CWE-787: Out-of-bounds Write •

CVE-2021-41160 – Improper region checks in FreeRDP allow out of bound write to memory
https://notcve.org/view.php?id=CVE-2021-41160
21 Oct 2021 — 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) ... • https://github.com/Jajangjaman/CVE-2021-41160 • CWE-787: Out-of-bounds Write •

CVE-2020-15103 – Integer Overflow in FreeRDP
https://notcve.org/view.php?id=CVE-2020-15103
27 Jul 2020 — 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 En FreeRDP versiones ante... • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00010.html • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow •
