Tor Browser 6.0.7 is released
This release features an important security update to Firefox and contains, in addition to that, an update to NoScript (18.104.22.168).
The security flaw responsible for this urgent release is already actively exploited on Windows systems. Even though there is currently, to the best of our knowledge, no similar exploit for OS X or Linux users available the underlying bug affects those platforms as well. Thus we strongly recommend that all users apply the update to their Tor Browser immediately. A restart is required for it to take effect.
Tor Browser users who had set their security slider to "High" are believed to have been safe from this vulnerability.
We will have alpha and hardened Tor Browser updates out shortly. In the meantime, users of these series can mitigate the security flaw in at least two ways:
1) Set the security slider to "High" as this is preventing the exploit from working.
2) Switch to the stable series until updates for alpha and hardened are available, too.
Here is the full changelog since 6.0.6:
- All Platforms
- Update Firefox to 45.5.1esr
- Update NoScript to 22.214.171.124
