This is a demonstration of the Warning: Unsafe Paste feature of the Xfce Terminal Emulator. Other graphical terminal emulators might have similar features.

Figure: Warning: Unsafe Paste feature

First a text editor is opened, then several arbitrary lines of text written, copied to clipboard and pasted into the terminal emulator.

1. Open a text editor.

Open file some-file-name in a text editor of your choice as a regular, non-root user.

If you are using a graphical environment, run. mousepad some-file-name

If you are using a terminal, run. nano some-file-name

2. Write several lines of text.

Should be long lines. Should be multiple lines. The text is not important. Can be anything.

For example:

111111111111111111111111 222222222222222222222222

3. Copy to clipboard.

Select all of the lines of text and right click, copy to clipboard.

4. Open a terminal.

Open a terminal.

If you are using Kicksecure inside Qubes, complete the following steps.

Qubes App Launcher (blue/grey "Q") → Kicksecure App Qube (commonly named kicksecure) → Xfce Terminal

If you are using a graphical Kicksecure with Xfce, run.

Start Menu → Xfce Terminal

5. Paste the text into the terminal.

6. The warning popup will appear.

Warning: Unsafe Paste

7. Done.

The demonstration of the Warning: Unsafe Paste feature has been completed.

Note: Replace /path/to/file with the actual file name.

Footnotes[edit]

↑ Kicksecure means all Kicksecure platforms except Kicksecure inside Qubes. This includes Kicksecure on hardware, Kicksecure in VMs such as VirtualBox, Kicksecure KVM.
↑ However, unrestricted access to the large number of codecs, along with the gstreamer and ffmpeg frameworks can expose the system to remote attacks. The risk is greater than with Tor Browser because the latter attempts to restrict codecs to a particular subset.
