Can I be attacked just by being connected to the internet?
Ubuntu is going to come with Nvidia drivers default, then news of possible exploits comes up. Compaines start producing Mac OS X virus programs news about OS X virus start popping up everywhere. Something smells fishy
Seems like the fix is already released for Dapper and Edgy: https://launchpad.net/distros/ubuntu....17/+bug/46034 (see status) so you shouldn't have any problems if you recently updated your system. Anyhow, assuming you still have the vulnerable driver:
probably no if you don't accept remote X connections:
I don't think anyone out there could send some glyph data to your X client just because you're online. But then again, I don't really know what I'm talking about...It is important to note that glyph data is supplied to the X server
by the X client. Any remote X client can gain root privileges on
the X server using the proof of concept program attached.
It is also trivial to exploit this vulnerability as a DoS by causing
an existing X client program (such as Firefox) to render a long text
string. It may be possible to use Flash movies, Java applets, or
embedded web fonts to supply the custom glyph data necessary for
reliable remote code execution.
A simple HTML page containing an INPUT field with a long value is
sufficient to demonstrate the DoS.
