+Changes in version 0.4.3.3-alpha - 2020-03-18
+ Tor 0.4.3.3-alpha fixes several bugs in previous releases, including
+ TROVE-2020-002, a major denial-of-service vulnerability that affected
+ all released Tor instances since 0.2.1.5-alpha. Using this
+ vulnerability, an attacker could cause Tor instances to consume a huge
+ amount of CPU, disrupting their operations for several seconds or
+ minutes. This attack could be launched by anybody against a relay, or
+ by a directory cache against any client that had connected to it. The
+ attacker could launch this attack as much as they wanted, thereby
+ disrupting service or creating patterns that could aid in traffic
+ analysis. This issue was found by OSS-Fuzz, and is also tracked
+ as CVE-2020-10592.
+
+ We do not have reason to believe that this attack is currently being
+ exploited in the wild, but nonetheless we advise everyone to upgrade
+ as soon as packages are available.
+
+ o Major bugfixes (security, denial-of-service):
+ - Fix a denial-of-service bug that could be used by anyone to
+ consume a bunch of CPU on any Tor relay or authority, or by
+ directories to consume a bunch of CPU on clients or hidden
+ services. Because of the potential for CPU consumption to
+ introduce observable timing patterns, we are treating this as a
+ high-severity security issue. Fixes bug 33119; bugfix on
+ 0.2.1.5-alpha. Found by OSS-Fuzz. We are also tracking this issue
+ as TROVE-2020-002 and CVE-2020-10592.
+
+ o Major bugfixes (circuit padding, memory leak):
+ - Avoid a remotely triggered memory leak in the case that a circuit
+ padding machine is somehow negotiated twice on the same circuit.
+ Fixes bug 33619; bugfix on 0.4.0.1-alpha. Found by Tobias Pulls.
+ This is also tracked as TROVE-2020-004 and CVE-2020-10593.
+
+ o Major bugfixes (directory authority):
+ - Directory authorities will now send a 503 (not enough bandwidth)
+ code to clients when under bandwidth pressure. Known relays and
+ other authorities will always be answered regardless of the
+ bandwidth situation. Fixes bug 33029; bugfix on 0.1.2.5-alpha.
+
+ o Minor features (diagnostic):
+ - Improve assertions and add some memory-poisoning code to try to
+ track down possible causes of a rare crash (32564) in the EWMA
+ code. Closes ticket 33290.
+
+ o Minor features (directory authorities):
+ - Directory authorities now reject descriptors from relays running
+ Tor versions from the 0.2.9 and 0.4.0 series. The 0.3.5 series is
+ still allowed. Resolves ticket 32672. Patch by Neel Chauhan.
+
+ o Minor features (usability):
+ - Include more information when failing to parse a configuration
+ value. This should make it easier to tell what's going wrong when
+ a configuration file doesn't parse. Closes ticket 33460.
+
+ o Minor bugfix (relay, configuration):
+ - Warn if the ContactInfo field is not set, and tell the relay
+ operator that not having a ContactInfo field set might cause their
+ relay to get rejected in the future. Fixes bug 33361; bugfix
+ on 0.1.1.10-alpha.
+
+ o Minor bugfixes (coding best practices checks):
+ - Allow the "practracker" script to read unicode files when using
+ Python 2. We made the script use unicode literals in 0.4.3.1-alpha,
+ but didn't change the codec for opening files. Fixes bug 33374;
+ bugfix on 0.4.3.1-alpha.
+
+ o Minor bugfixes (continuous integration):
+ - Remove the buggy and unused mirroring job. Fixes bug 33213; bugfix
+ on 0.3.2.2-alpha.
+
+ o Minor bugfixes (onion service v3, client):
+ - Remove a BUG() warning that would cause a stack trace if an onion
+ service descriptor was freed while we were waiting for a
+ rendezvous circuit to complete. Fixes bug 28992; bugfix
+ on 0.3.2.1-alpha.
+
+ o Minor bugfixes (onion services v3):
+ - Fix an assertion failure that could result from a corrupted
+ ADD_ONION control port command. Found by Saibato. Fixes bug 33137;
+ bugfix on 0.3.3.1-alpha. This issue is also tracked
+ as TROVE-2020-003.
+
+ o Documentation (manpage):
+ - Alphabetize the Server and Directory server sections of the tor
+ manpage. Also split Statistics options into their own section of
+ the manpage. Closes ticket 33188. Work by Swati Thacker as part of
+ Google Season of Docs.
+ - Document the __OwningControllerProcess torrc option and specify
+ its polling interval. Resolves issue 32971.
+
+ o Testing (Travis CI):
+ - Remove a redundant distcheck job. Closes ticket 33194.
+ - Sort the Travis jobs in order of speed: putting the slowest jobs
+ first takes full advantage of Travis job concurrency. Closes
+ ticket 33194.
+ - Stop allowing the Chutney IPv6 Travis job to fail. This job was
+ previously configured to fast_finish (which requires
+ allow_failure), to speed up the build. Closes ticket 33195.
+ - When a Travis chutney job fails, use chutney's new "diagnostics.sh"
+ tool to produce detailed diagnostic output. Closes ticket 32792.
