Changes in version 0.2.8.8 - 2016-09-23
Tor 0.2.8.8 fixes two crash bugs present in previous versions of the
0.2.8.x series. Relays running 0.2.8.x should upgrade, as should users
who select public relays as their bridges.
o Major bugfixes (crash):
- Fix a complicated crash bug that could affect Tor clients
configured to use bridges when replacing a networkstatus consensus
in which one of their bridges was mentioned. OpenBSD users saw
more crashes here, but all platforms were potentially affected.
Fixes bug 20103; bugfix on 0.2.8.2-alpha.
o Major bugfixes (relay, OOM handler):
- Fix a timing-dependent assertion failure that could occur when we
tried to flush from a circuit after having freed its cells because
of an out-of-memory condition. Fixes bug 20203; bugfix on
0.2.8.1-alpha. Thanks to "cypherpunks" for help diagnosing
this one.
o Minor feature (fallback directories):
- Remove broken fallbacks from the hard-coded fallback directory
list. Closes ticket 20190; patch by teor.
o Minor features (geoip):
- Update geoip and geoip6 to the September 6 2016 Maxmind GeoLite2
Country database.

Tor Browser 6.0.5 is now available from the Tor Browser Project page [1]
and also from our distribution directory [2].

This release features important security updates to Firefox including
the recently disclosed extension update vulnerability [3]. All users
should upgrade as soon as possible.

That vulnerability [4] allows an …
[View More]attacker who is able to obtain a valid
certificate for addons.mozilla.org to impersonate Mozilla's servers and
to deliver a malicious extension update, e.g. for NoScript. This could
lead to arbitrary code execution. Moreover, other built-in certificate
pinnings are affected as well. Obtaining such a certificate is not an
easy task, but it's within reach of powerful adversaries (e.g. nation states).

Thanks to everyone who helped investigating this bug and getting a bugfix
release out as fast as possible.
We are currently building the alpha and hardened bundles (6.5a3 and
6.5a3-hardened) that will contain the fix for alpha/hardened channel
users. We expect them to get released at the beginning of next week.
Until then users are strongly encouraged to use Tor Browser 6.0.5.
