All Tor users should upgrade to this release, or + to another of the releases coming out today. + + Note: the Tor 0.2.8 series will no longer be supported after 1 Jan + 2018. If you need a release with long-term support, please stick with + the 0.2.9 series. Otherwise, please upgrade to 0.3.1 or later. + + o Major bugfixes (security, backport from 0.3.2.6-alpha): + - Fix a denial of service bug where an attacker could use a + malformed directory object to cause a Tor instance to pause while + OpenSSL would try to read a passphrase from the terminal. (Tor + instances run without a terminal, which is the case for most Tor + packages, are not impacted.) Fixes bug 24246; bugfix on every + version of Tor. Also tracked as TROVE-2017-011 and CVE-2017-8821. + Found by OSS-Fuzz as testcase 6360145429790720. + - When checking for replays in the INTRODUCE1 cell data for a + (legacy) onion service, correctly detect replays in the RSA- + encrypted part of the cell. We were previously checking for + replays on the entire cell, but those can be circumvented due to + the malleability of Tor's legacy hybrid encryption. This fix helps + prevent a traffic confirmation attack. Fixes bug 24244; bugfix on + 0.2.4.1-alpha. This issue is also tracked as TROVE-2017-009 + and CVE-2017-8819. + + o Major bugfixes (security, onion service v2, backport from 0.3.2.6-alpha): + - Fix a use-after-free error that could crash v2 Tor onion services + when they failed to open circuits while expiring introduction + points. Fixes bug 24313; bugfix on 0.2.7.2-alpha. This issue is + also tracked as TROVE-2017-013 and CVE-2017-8823. + + o Major bugfixes (security, relay, backport from 0.3.2.6-alpha): + - When running as a relay, make sure that we never build a path through + ourselves, even in the case where we have somehow lost the version of + our descriptor appearing in the consensus. Fixes part of bug 21534; + bugfix on 0.2.0.1-alpha. This issue is also tracked as TROVE-2017-012 + and CVE-2017-8822. + + o Minor features (bridge, backport from 0.3.1.9): + - Bridges now include notice in their descriptors that they are + bridges, and notice of their distribution status, based on their + publication settings. Implements ticket 18329. For more fine- + grained control of how a bridge is distributed, upgrade to 0.3.2.x + or later. + + o Minor features (directory authority, backport from 0.3.2.6-alpha): + - Add an IPv6 address for the "bastet" directory authority. Closes + ticket 24394. + + o Minor features (geoip): + - Update geoip and geoip6 to the November 6 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (testing, backport from 0.3.1.6-rc): + - Fix an undersized buffer in test-memwipe.c. Fixes bug 23291; + bugfix on 0.2.7.2-alpha. Found and patched by Ties Stuij. + + Changes in version 0.2.8.16 - 2017-10-25 Tor 0.2.8.16 backports a collection of bugfixes from later Tor release series, including a bugfix for a crash issue that had affected relays diff --git a/changes/bastet_v6 b/changes/bastet_v6 deleted file mode 100644 index ee4e2c809..000000000 --- a/changes/bastet_v6 +++ /dev/null @@ -1,4 +0,0 @@ - o Minor features (directory authority): - - Add an IPv6 address for the "bastet" directory authority. - Closes ticket 24394. - diff --git a/changes/bug18329-minimal b/changes/bug18329-minimal deleted file mode 100644 index 804c4e8dd..000000000 --- a/changes/bug18329-minimal +++ /dev/null @@ -1,6 +0,0 @@ - o Minor features (bridge): - - Bridges now include notice in their descriptors that they are bridges, - and notice of their distribution status, based on their publication - settings.
