+Changes in version 0.3.2.6-alpha - 2017-12-01
|
|
|
+ This version of Tor is the latest in the 0.3.2 alpha series. It
|
|
|
+ includes fixes for several important security issues. All Tor users
|
|
|
+ should upgrade to this release, or to one of the other releases coming
|
|
|
+ out today.
|
|
|
+
|
|
|
+ o Major bugfixes (security):
|
|
|
+ - 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):
|
|
|
+ - 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):
|
|
|
+ - 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.
|
|
|
+ - When running as a relay, make sure that we never choose ourselves
|
|
|
+ as a guard. Fixes part of bug 21534; bugfix on 0.3.0.1-alpha. This
|
|
|
+ issue is also tracked as TROVE-2017-012 and CVE-2017-8822.
|
|
|
+
|
|
|
+ o Minor feature (relay statistics):
|
|
|
+ - Change relay bandwidth reporting stats interval from 4 hours to 24
|
|
|
+ hours in order to reduce the efficiency of guard discovery
|
|
|
+ attacks. Fixes ticket 23856.
|
|
|
+
|
|
|
+ o Minor features (directory authority):
|
|
|
+ - Add an IPv6 address for the "bastet" directory authority. Closes
|
|
|
+ ticket 24394.
|
|
|
+
|
|
|
+ o Minor bugfixes (client):
|
|
|
+ - By default, do not enable storage of client-side DNS values. These
|
|
|
+ values were unused by default previously, but they should not have
|
|
|
+ been cached at all. Fixes bug 24050; bugfix on 0.2.6.3-alpha.
|
|
|
+
|
|
|
+
|
|
|
+Changes in version 0.3.1.9 - 2017-12-01:
|
|
|
+ Tor 0.3.1.9 backports important security and stability fixes from the
|
|
|
+ 0.3.2 development series. All Tor users should upgrade to this
|
|
|
+ release, or to another of the releases coming out today.
|
|
|
+
|
|
|
+ o Major bugfixes (security, backport from 0.3.2.6-alpha):
|
|

|
|
|
+
|
|
|
+ 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
|
|
|

|
|
+ issue is also tracked as TROVE-2017-012 and CVE-2017-8822.
|
|
|
+
|
|
|
+ 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 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. 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 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 (onion service, backport from 0.3.2.5-alpha):
|
|
|
+ - Rename the consensus parameter "hsdir-interval" to "hsdir_interval"
|
|
|
+ so it matches dir-spec.txt. Fixes bug 24262; bugfix
|
|
|
+ on 0.3.1.1-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.
|
|
|
+
|
|
|
+
|
|
|
+Changes in version 0.3.0.13 - 2017-12-01

+ to another of the releases coming out today.
|
|
|
+

|
|
|
+
|
|
|
+ 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.

+ 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.

+Changes in version 0.2.8.17 - 2017-12-01
|
|
|
+ Tor 0.2.8.17 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.
|
|
|
+
|
|
|
+ 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 upgrade 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;
