    Tor 0.2.8.9 backports a fix for a security hole in previous versions of Tor that would allow a remote attacker to crash a Tor client, hidden service, relay, or authority. All Tor users should upgrade to this version, or to 0.2.9.4-alpha. Patches will be released for older versions of Tor.

    You can download the source from the Tor website. Packages should be available over the next week or so.

    Below is a list of changes since 0.2.8.8.

    Changes in version 0.2.8.9 - 2016-10-17

    • Major features (security fixes, also in 0.2.9.4-alpha):
      • Prevent a class of security bugs caused by treating the contents of a buffer chunk as if they were a NUL-terminated string. At least one such bug seems to be present in all currently used versions of Tor, and would allow an attacker to remotely crash most Tor instances, especially those compiled with extra compiler hardening. With this defense in place, such bugs can't crash Tor, though we should still fix them as they occur. Closes ticket 20384 (TROVE-2016-10-001).
    • Minor features (geoip):
      • Update geoip and geoip6 to the October 4 2016 Maxmind GeoLite2 Country database.
