CVE-2022-24882 2 Fedoraproject, Freerdp 3 Extra Packages For Enterprise Linux, Fedora, Freerdp 2024-02-28 5.0 MEDIUM 7.5 HIGH
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. RDP clients are not affected. The vulnerability is patched in FreeRDP 2.7.0. There are currently no known workarounds.
CVE-2022-24883 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2024-02-28 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-2021-41159 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2024-02-28 6.8 MEDIUM 8.8 HIGH
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.
CVE-2021-41160 2 Fedoraproject, Freerdp 2 Fedora, Freerdp 2024-02-28 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.
CVE-2021-37594 2 Freerdp, Microsoft 2 Freerdp, Windows 2024-02-28 7.5 HIGH 9.8 CRITICAL

CVE-2020-11041 3 Debian, Freerdp, Opensuse 3 Debian Linux, Freerdp, Leap 2024-02-28 4.0 MEDIUM 2.7 LOW
In FreeRDP less than or equal to 2.0.0, an outside controlled array index is used unchecked for data used as configuration for sound backend (alsa, oss, pulse, ...). The most likely outcome is a crash of the client instance followed by no or distorted sound or a session disconnect. If a user cannot upgrade to the patched version, a workaround is to disable sound for the session. This has been patched in 2.1.0.
CVE-2020-11085 3 Debian, Freerdp, Opensuse 3 Debian Linux, Freerdp, Leap 2024-02-28 5.0 MEDIUM 3.5 LOW
