Well, any file parsing bug could be considered a "remote"
vulnerability if you consider the prospect of downloading a malicious
file from the internet.
I don't think that remote X clients are an issue; the last time I
checked, the driver in question was only used for direct rendering,
which requires a local X client, while indirect rendering uses the
built-in software renderer.
