+Changes in version 0.2.9.14 - 2017-12-01
+ Tor 0.3.0.13 backports important security and stability bugfixes from
+ later Tor releases. All Tor users should upgrade to this release, or
+ to another of the releases coming out today.
+
+ o Major bugfixes (exit relays, DNS, backport from 0.3.2.4-alpha):
+ - Fix an issue causing DNS to fail on high-bandwidth exit nodes,
+ making them nearly unusable. Fixes bugs 21394 and 18580; bugfix on
+ 0.1.2.2-alpha, which introduced eventdns. Thanks to Dhalgren for
+ identifying and finding a workaround to this bug and to Moritz,
+ Arthur Edelstein, and Roger for helping to track it down and
+ analyze it.
+
+ 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.
+ - Fix a denial of service issue where an attacker could crash a
+ directory authority using a malformed router descriptor. Fixes bug
+ 24245; bugfix on 0.2.9.4-alpha. Also tracked as TROVE-2017-010
+ and CVE-2017-8820.
+ - 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 features (security, windows, backport from 0.3.1.1-alpha):
+ - Enable a couple of pieces of Windows hardening: one
+ (HeapEnableTerminationOnCorruption) that has been on-by-default
+ since Windows 8, and unavailable before Windows 7; and one
+ (PROCESS_DEP_DISABLE_ATL_THUNK_EMULATION) which we believe doesn't
+ affect us, but shouldn't do any harm. Closes ticket 21953.
+
+ o Minor bugfix (relay address resolution, backport from 0.3.2.1-alpha):
+ - Avoid unnecessary calls to directory_fetches_from_authorities() on
+ relays, to prevent spurious address resolutions and descriptor
+ rebuilds. This is a mitigation for bug 21789. Fixes bug 23470;
+ bugfix on in 0.2.8.1-alpha.
+
+ o Minor bugfixes (compilation, backport from 0.3.2.1-alpha):
+ - Fix unused variable warnings in donna's Curve25519 SSE2 code.
+ Fixes bug 22895; bugfix on 0.2.7.2-alpha.
+
+ o Minor bugfixes (logging, relay shutdown, annoyance, backport from 0.3.2.2-alpha):
+ - When a circuit is marked for close, do not attempt to package any
+ cells for channels on that circuit. Previously, we would detect
+ this condition lower in the call stack, when we noticed that the
+ circuit had no attached channel, and log an annoying message.
+ Fixes bug 8185; bugfix on 0.2.5.4-alpha.
+
+ o Minor bugfixes (relay, crash, backport from 0.3.2.4-alpha):
+ - Avoid a crash when transitioning from client mode to bridge mode.
+ Previously, we would launch the worker threads whenever our
+ "public server" mode changed, but not when our "server" mode
+ changed. Fixes bug 23693; bugfix on 0.2.6.3-alpha.
+
+ 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.
+
