The use of D-Bus is great -because it allows to implement discovery and signaling. - -The D-Bus session is by default addressed by environment variable -`DBUS_SESSION_BUS_ADDRESS`. Using **systemd** variable `DBUS_SESSION_BUS_ADDRESS` -is automatically set for user sessions. D-Bus usage is linked to permissions. - -D-Bus has already had several [security issues](https://www.cvedetails.com/vulnerability-list/vendor_id-13442/D-bus-Project.html) -(mostly **DoS** issues), to allow applications to keep talking to each other. -It is important to protect against this type of attack to keep the system more -stable. - - -<!-- section-config --> - -Domain | Object | Recommendations ---------------- | -------------- | ------------------------------------ -Platform-DBus-1 | Security model | Use D-Bus as IPC. -Platform-DBus-2 | Security model | Apply D-BUS security patches: [D-Bus CVE](https://www.cvedetails.com/vulnerability-list/vendor_id-13442/D-bus-Project.html) - -<!-- end-section-config --> |
