This release is an emergency release to fix security vulnerabilities in *Tor Browser* and *Tor*.
You should upgrade as soon as possible.
[[!toc levels=1]]
Included software
Update *Tor Browser* to [9.0.7](https://blog.torproject.org/new-release-tor-browser-907), which prevents [[JavaScript from sometimes being enabled in the *Safest* security level of Tor Browser|news/javascript_sometimes_enabled_in_safest]].
Update *Tor* to [](https://blog.torproject.org/new-releases-03510-0419-0427), which fixes TROVE-2020-002, a major denial-of-service vulnerability that affects both Tor relays and clients. Using this vulnerability, an attacker could cause Tor to consume a huge amount of CPU, disrupting its operations for several seconds or minutes, and create patterns that could aid in traffic analysis.
- Update *Thunderbird* to [68.6.0](https://www.thunderbird.net/en-US/thunderbird/68.6.0/releasenotes/).
