This release is an emergency release to fix security vulnerabilities in Tor Browser and Tor.

You should upgrade as soon as possible.

Included software

• Update Tor Browser to 9.0.7, which prevents JavaScript from sometimes being enabled in the Safest security level of Tor Browser.

• Update Tor to 0.4.2.7, 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.
