What is FreeRDP?

FreeRDP is a free implementation of RDP for Linux. FreeRDP is a new project with the goal to be a free replacement for Microsoft RDP (Remote Desktop Protocol). FreeRDP has been tested on various platforms and all builds are signed with our official key, so it can be used on Windows, Mac OS X, and Linux without any worries. FreeRDP 1.x is based on Red Hat's rexdm server while version 2.0 is based on rexdmn client/server.

Debian Bug

The Debian Project reports that FreeRDP, the software that provides remote desktop functionality to applications compatible with Microsoft Windows, is vulnerable to Remote Code Execution. This bug can be triggered by sending a specially crafted sequence of packets to the server. A similar vulnerability was reported in May 2017.
FreeRDP files are not included in Debian’s standard repositories and must be installed from an external source such as one of our own installation packages or the source code on our website.
