Changes in version 0.3.3.3-alpha - 2018-03-03
Tor 0.3.3.3-alpha is the third alpha release for the 0.3.3.x series.
It includes an important security fix for a remote crash attack
against directory authorities tracked as TROVE-2018-001.
Additionally, with this release, we are upgrading the severity of a
bug fixed in 0.3.3.2-alpha. Bug 24700, which was fixed in
0.3.3.2-alpha, can be remotely triggered in order to crash relays with
a use-after-free pattern. As such, we are now tracking that bug as
TROVE-2018-002 and CVE-2018-0491. This bug affected versions
0.3.2.1-alpha through 0.3.2.9, as well as 0.3.3.1-alpha.
This release also fixes several minor bugs and annoyances from
earlier releases.
Relays running 0.3.2.x should upgrade to one of the versions released
today, for the fix to TROVE-2018-002. Directory authorities should
also upgrade. (Relays on earlier versions might want to update too for
the DoS mitigations.)
o Major bugfixes (denial-of-service, directory authority):
- Fix a protocol-list handling bug that could be used to remotely crash
directory authorities with a null-pointer exception. Fixes bug 25074;
bugfix on 0.2.9.4-alpha. Also tracked as TROVE-2018-001 and
CVE-2018-0490.
o Minor features (compatibility, OpenSSL):
- Tor will now support TLS1.3 once OpenSSL 1.1.1 is released.
Previous versions of Tor would not have worked with OpenSSL 1.1.1,
since they neither disabled TLS 1.3 nor enabled any of the
ciphersuites it requires. Now we enable the TLS 1.3 ciphersuites.
Closes ticket 24978.
o Minor features (logging):
- Clarify the log messages produced when getrandom() or a related
entropy-generation mechanism gives an error. Closes ticket 25120.
o Minor features (testing):
- Add a "make test-rust" target to run the rust tests only. Closes
ticket 25071.
o Minor bugfixes (denial-of-service):
- Fix a possible crash on malformed consensus. If a consensus had
contained an unparseable protocol line, it could have made clients
and relays crash with a null-pointer exception. To exploit this
issue, however, an attacker would need to be able to subvert the
directory authority system. Fixes bug 25251; bugfix on
0.2.9.4-alpha. Also tracked as TROVE-2018-004.
o Minor bugfixes (DoS mitigation):
- Add extra safety checks when refilling the circuit creation bucket
to ensure we never set a value above the allowed maximum burst.
Fixes bug 25202; bugfix on 0.3.3.2-alpha.
- When a new consensus arrives, don't update our DoS-mitigation
parameters if we aren't a public relay. Fixes bug 25223; bugfix
on 0.3.3.2-alpha.
o Minor bugfixes (man page, SocksPort):
- Remove dead code from the old "SocksSocket" option, and rename
SocksSocketsGroupWritable to UnixSocksGroupWritable. The old option
still works, but is deprecated. Fixes bug 24343; bugfix on 0.2.6.3.
o Minor bugfixes (performance):
- Reduce the number of circuits that will be opened at once during
the circuit build timeout phase. This is done by increasing the
idle timeout to 3 minutes, and lowering the maximum number of
concurrent learning circuits to 10. Fixes bug 24769; bugfix
on 0.3.1.1-alpha.
o Minor bugfixes (spec conformance):
- Forbid "-0" as a protocol version. Fixes part of bug 25249; bugfix on
0.2.9.4-alpha.
- Forbid UINT32_MAX as a protocol version. Fixes part of bug 25249;
bugfix on 0.2.9.4-alpha.
o Minor bugfixes (spec conformance, rust):
- Resolve a denial-of-service issue caused by an infinite loop in
the rust protover code. Fixes bug 25250, bugfix on 0.3.3.1-alpha.
Also tracked as TROVE-2018-003.
o Code simplification and refactoring:
- Update the "rust dependencies" submodule to be a project-level
repository, rather than a user repository. Closes ticket 25323.
