Hi, all! There is a new stable release of the Tor source code, with
fixes for a security bug. You should probably upgrade as packages
become available.
(If you are about to reply saying "please take me off this list",
instead please follow these instructions:

You can download the source from the usual place on the website.
Packages should be up within a few days.
If you maintain an older version of Tor, you can find backported
patches for this fix at
https://trac.torproject.org/projects/tor/ticket/20384
====
Changes in version 0.2.8.9 - 2016-10-17
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.
o 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).
o Minor features (geoip):
- Update geoip and geoip6 to the October 4 2016 Maxmind GeoLite2
Country database.
