9 <p>This security issue was fixed in Tails 0.9.</p>
14 currently shipped in Tails does not protect your anonymity as it should.
15 **This vulnerability is critical.**
17 Until a future version of Tails is released (soon), the only way to
18 have Tails protect your anonymity is to **upgrade Tor every time you
19 start Tails**, by following the instructions bellow.
21 (Every time, really? Sure. Tails is amnesic: any change you make in it
22 is lost upon restart.)
24 To upgrade Tor, start a *Root Terminal* from the
25 *Applications* → *Accessories* menu, and type the following command in
28 apt-get update && apt-get install tor && service tor start
30 ... then type *Enter*, and wait until the upgrade is completed, which
31 may take a few minutes. At this time, the Vidalia icon on the top
32 right of the screen should have changed from the usual green onion to
33 a grey, red-crossed one. Right click on it and choose *Exit* in the
34 menu that opens. Then, start a new Vidalia from the
35 *Applications* → *Internet* menu.
37 Once this is done, you can safely use Tails as usual.
