Fedora 35: 2021-11-17 Security Advisory for Guacamole-Server

Guacamole is an HTML5 remote desktop gateway.

Guacamole provides access to desktop environments using remote desktop protocols

like VNC and RDP. A centralized server acts as a tunnel and proxy, allowing

access to multiple desktops through a web browser.

No browser plugins are needed, and no client software needs to be installed. The

client requires nothing more than a web browser supporting HTML5 and AJAX.

The main web application is provided by the "guacamole-client" package.
