+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): + - 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. + - 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 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 0.3.1.8 - 2017-10-25 Tor 0.3.1.8 is the second stable release in the 0.3.1 series. It includes several bugfixes, including a bugfix for a crash issue
