CVE-2023-39351 4 Debian, Fedoraproject, Freerdp and 1 more 4 Debian Linux, Fedora, Freerdp and 1 more 2024-11-21 5.3 Medium
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. Affected versions of FreeRDP are subject to a Null Pointer Dereference leading a crash in the RemoteFX (rfx) handling. Inside the `rfx_process_message_tileset` function, the program allocates tiles using `rfx_allocate_tiles` for the number of numTiles. If the initialization process of tiles is not completed for various reasons, tiles will have a NULL pointer. Which may be accessed in further processing and would cause a program crash. This issue has been addressed in versions 2.11.0 and 3.0.0-beta3. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2023-39350 4 Debian, Fedoraproject, Freerdp and 1 more 4 Debian Linux, Fedora, Freerdp and 1 more 2024-11-21 5.9 Medium
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. This issue affects Clients only.

CVE-2022-39283 3 Fedoraproject, Freerdp, Redhat 3 Fedora, Freerdp, Enterprise Linux 2024-11-21 5.9 Medium
FreeRDP is a free remote desktop protocol library and clients. All FreeRDP based clients when using the `/video` command line switch might read uninitialized data, decode it as audio/video and display the result. FreeRDP based server implementations are not affected. This issue has been patched in version 2.8.1. If you cannot upgrade do not use the `/video` switch.

If unable to upgrade, do not use parallel port redirection (`/parallel` command line switch) as a workaround.
CVE-2022-24883 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2024-11-21 7.4 High
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-2022-24882 2 Fedoraproject, Freerdp 3 Extra Packages For Enterprise Linux, Fedora, Freerdp 2024-11-21 9.1 Critical
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP). In versions prior to 2.7.0, NT LAN Manager (NTLM) authentication does not properly abort when someone provides and empty password value. This issue affects FreeRDP based RDP Server implementations.

CVE-2021-41160 3 Fedoraproject, Freerdp, Redhat 4 Fedora, Freerdp, Enterprise Linux and 1 more 2024-11-21 5.3 Medium
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.
CVE-2021-41159 3 Fedoraproject, Freerdp, Redhat 4 Fedora, Freerdp, Enterprise Linux and 1 more 2024-11-21 5.8 Medium
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.
