| CVE-2024-22211 | 1 Freerdp | 1 Freerdp | 2024-02-17 | N/A | 9.8 CRITICAL |
| FreeRDP is a set of free and open source remote desktop protocol library and clients. In affected versions an integer overflow in `freerdp_bitmap_planar_context_reset` leads to heap-buffer overflow. This affects FreeRDP based clients. FreeRDP based server implementations and proxy are not affected. A malicious server could prepare a `RDPGFX_RESET_GRAPHICS_PDU` to allocate too small buffers, possibly triggering later out of bound read/write. Data extraction over network is not possible, the buffers are used to display an image. This issue has been addressed in version 2.11.5 and 3.2.0. Users are advised to upgrade. there are no know workarounds for this vulnerability. | |||||

| FreeRDP is a free remote desktop protocol library and clients. FreeRDP based clients on unix systems using `/parallel` command line switch might read uninitialized data and send it to the server the client is currently connected to. FreeRDP based server implementations are not affected. Please upgrade to 2.8.1 where this issue is patched.

| CVE-2022-24883 | 2 Fedoraproject, Freerdp | 2 Fedora, Freerdp | 2024-02-04 | 6.8 MEDIUM | 9.8 CRITICAL |
| FreeRDP is a free implementation of the Remote Desktop Protocol (RDP). Prior to version 2.7.0, server side authentication against a `SAM` file might be successful for invalid credentials if the server has configured an invalid `SAM` file path. FreeRDP based clients are not affected. RDP server implementations using FreeRDP to authenticate against a `SAM` file are affected. Version 2.7.0 contains a fix for this issue. As a workaround, use custom authentication via `HashCallback` and/or ensure the `SAM` database path configured is valid and the application has file handles left. | |||||

| CVE-2021-41160 | 2 Fedoraproject, Freerdp | 2 Fedora, Freerdp | 2024-02-04 | 6.8 MEDIUM | 8.8 HIGH |
| 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. | |||||

| 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. | |||||
