Anyone running an earlier version of Tor 0.3.3 should upgrade + to this version, or to a later series. + + As a reminder, support the Tor 0.3.3 series will end on 22 Feb 2019. + We anticipate that this will be the last release of Tor 0.3.3, unless + some major bug is before then. Some time between now and then, users + should switch to either the Tor 0.3.4 series (supported until at least + 10 June 2019), or the Tor 0.3.5 series, which will receive long-term + support until at least 1 Feb 2022. + + o Major bugfixes (OpenSSL, portability, backport from 0.3.5.5-alpha): + - Fix our usage of named groups when running as a TLS 1.3 client in + OpenSSL 1.1.1. Previously, we only initialized EC groups when + running as a relay, which caused clients to fail to negotiate TLS + 1.3 with relays. Fixes bug 28245; bugfix on 0.2.9.15 (when TLS 1.3 + support was added). + + o Major bugfixes (restart-in-process, backport from 0.3.5.1-alpha): + - Fix a use-after-free error that could be caused by passing Tor an + impossible set of options that would fail during options_act(). + Fixes bug 27708; bugfix on 0.3.3.1-alpha. + + o Minor features (continuous integration, backport from 0.3.5.1-alpha): + - Only run one online rust build in Travis, to reduce network + errors. Skip offline rust builds on Travis for Linux gcc, because + they're redundant. Implements ticket 27252. + - Skip gcc on OSX in Travis CI, because it's rarely used. Skip a + duplicate hardening-off build in Travis on Tor 0.2.9. Skip gcc on + Linux with default settings, because all the non-default builds + use gcc on Linux. Implements ticket 27252. + + o Minor features (continuous integration, backport from 0.3.5.3-alpha): + - Use the Travis Homebrew addon to install packages on macOS during + Travis CI. The package list is the same, but the Homebrew addon + does not do a `brew update` by default. Implements ticket 27738. + + o Minor features (fallback directory list, backport from 0.3.5.6-rc): + - Replace the 150 fallbacks originally introduced in Tor + 0.3.3.1-alpha in January 2018 (of which ~115 were still + functional), with a list of 157 fallbacks (92 new, 65 existing, 85 + removed) generated in December 2018. Closes ticket 24803. + + o Minor features (geoip): + - Update geoip and geoip6 to the January 3 2019 Maxmind GeoLite2 + Country database. Closes ticket 29012. + + o Minor features (OpenSSL bug workaround, backport from 0.3.5.7): + - Work around a bug in OpenSSL 1.1.1a, which prevented the TLS 1.3 + key export function from handling long labels. When this bug is + detected, Tor will disable TLS 1.3. We recommend upgrading to a + version of OpenSSL without this bug when it becomes available. + Closes ticket 28973. + + o Minor bugfixes (relay statistics, backport from 0.3.5.7): + - Update relay descriptor on bandwidth changes only when the uptime + is smaller than 24h, in order to reduce the efficiency of guard + discovery attacks. Fixes bug 24104; bugfix on 0.1.1.6-alpha. + + o Minor bugfixes (C correctness, backport from 0.3.5.4-alpha): + - Avoid undefined behavior in an end-of-string check when parsing + the BEGIN line in a directory object. Fixes bug 28202; bugfix + on 0.2.0.3-alpha. + + o Minor bugfixes (code safety, backport from 0.3.5.3-alpha): + - Rewrite our assertion macros so that they no longer suppress the + compiler's -Wparentheses warnings. Fixes bug 27709; bugfix + + o Minor bugfixes (compilation, backport from 0.3.5.5-alpha): + - Initialize a variable unconditionally in aes_new_cipher(), since + some compilers cannot tell that we always initialize it before + use. Fixes bug 28413; bugfix on 0.2.9.3-alpha. + + o Minor bugfixes (directory authority, backport from 0.3.5.4-alpha): + - Log additional info when we get a relay that shares an ed25519 ID + with a different relay, instead making a BUG() warning. Fixes bug + 27800; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (directory permissions, backport form 0.3.5.3-alpha): + - When a user requests a group-readable DataDirectory, give it to + them. Previously, when the DataDirectory and the CacheDirectory + were the same, the default setting (0) for + CacheDirectoryGroupReadable would override the setting for + DataDirectoryGroupReadable. Fixes bug 26913; bugfix + on 0.3.3.1-alpha. + + o Minor bugfixes (onion service v3, backport from 0.3.5.1-alpha): + - When the onion service directory can't be created or has the wrong + permissions, do not log a stack trace. Fixes bug 27335; bugfix + on 0.3.2.1-alpha. + + o Minor bugfixes (onion service v3, backport from 0.3.5.2-alpha): + - Close all SOCKS request (for the same .onion) if the newly fetched + descriptor is unusable. Before that, we would close only the first + one leaving the other hanging and let to time out by themselves. + Fixes bug 27410; bugfix on 0.3.2.1-alpha. + + o Minor bugfixes (onion service v3, backport from 0.3.5.3-alpha): + - Don't warn so loudly when Tor is unable to decode an onion + descriptor. This can now happen as a normal use case if a client + gets a descriptor with client authorization but the client is not + authorized. Fixes bug 27550; bugfix on 0.3.5.1-alpha. + + o Minor bugfixes (onion service v3, backport from 0.3.5.6-rc): + - When deleting an ephemeral onion service (DEL_ONION), do not close + any rendezvous circuits in order to let the existing client + connections finish by themselves or closed by the application. The + HS v2 is doing that already so now we have the same behavior for + all versions. Fixes bug 28619; bugfix on 0.3.3.1-alpha. + + o Minor bugfixes (HTTP tunnel): + - Fix a bug warning when closing an HTTP tunnel connection due to + an HTTP request we couldn't handle. Fixes bug 26470; bugfix on + 0.3.2.1-alpha. + + o Minor bugfixes (memory leaks, backport from 0.3.5.5-alpha): + - Fix a harmless memory leak in libtorrunner.a. Fixes bug 28419; + bugfix on 0.3.3.1-alpha. Patch from Martin Kepplinger. + + o Minor bugfixes (netflow padding, backport from 0.3.5.1-alpha): + - Ensure circuitmux queues are empty before scheduling or sending + padding. Fixes bug 25505; bugfix on 0.3.1.1-alpha. + + o Minor bugfixes (protover, backport from 0.3.5.3-alpha): + - Reject protocol names containing bytes other than alphanumeric + characters and hyphens ([A-Za-z0-9-]). Fixes bug 27316; bugfix + on 0.2.9.4-alpha. + + o Minor bugfixes (rust, backport from 0.3.5.1-alpha): + - Compute protover votes correctly in the rust version of the + protover code. Previously, the protover rewrite in 24031 allowed + repeated votes from the same voter for the same protocol version + to be counted multiple times in protover_compute_vote(). Fixes bug + 27649; bugfix on 0.3.3.5-rc. + - Reject protover names that contain invalid characters. Fixes bug + 27687; bugfix on 0.3.3.1-alpha. + + o Minor bugfixes (rust, backport from 0.3.5.2-alpha): + - protover_all_supported() would attempt to allocate up to 16GB on + some inputs, leading to a potential memory DoS. Fixes bug 27206; + bugfix on 0.3.3.5-rc. + + o Minor bugfixes (rust, backport from 0.3.5.4-alpha): + - Fix a potential null dereference in protover_all_supported(). Add + a test for it. Fixes bug 27804; bugfix on 0.3.3.1-alpha. + - Return a string that can be safely freed by C code, not one + created by the rust allocator, in protover_all_supported(). Fixes + bug 27740; bugfix on 0.3.3.1-alpha. + - Fix an API mismatch in the rust implementation of + protover_compute_vote(). This bug could have caused crashes on any + directory authorities running Tor with Rust (which we do not yet + recommend). Fixes bug 27741; bugfix on 0.3.3.6. + + o Minor bugfixes (testing, backport from 0.3.5.1-alpha): + - If a unit test running in a subprocess exits abnormally or with a + nonzero status code, treat the test as having failed, even if the + test reported success. Without this fix, memory leaks don't cause + the tests to fail, even with LeakSanitizer. Fixes bug 27658; + bugfix on 0.2.2.4-alpha. + + o Minor bugfixes (testing, backport from 0.3.5.4-alpha): + - Treat backtrace test failures as expected on BSD-derived systems + (NetBSD, OpenBSD, and macOS/Darwin) until we solve bug 17808. + (FreeBSD failures have been treated as expected since 18204 in + 0.2.8.) Fixes bug 27948; bugfix on 0.2.5.2-alpha. + + o Minor bugfixes (unit tests, guard selection, backport from 0.3.5.6-rc): + - Stop leaking memory in an entry guard unit test. Fixes bug 28554; + bugfix on 0.3.0.1-alpha. + + Changes in version 0.3.3.10 - 2018-09-10 Tor 0.3.3.10 backports numerous fixes from later versions of Tor. |
