pillule:
Hello,
I wonder how do you manage your computing life with the problem of the
clipboard / file sharing.
For example, the seemingly-innocent link that we
copy from an untrusted qube could turn out to be a large buffer of junk
that, when pasted into the target qube’s word processor, could exploit a
hypothetical bug in the undo buffer.
Qubes does show the number of bytes copied to the buffer when you
perform a shift-ctrl-c. If this is the same as the (small) number of
characters you are copying, chances of a successful attack fitting in 20
bytes or whatever is pretty slim. File sharing is a different matter,
can address somewhat by keeping your archive VM not network connected.
