Changes in version 0.4.4.4-rc - 2020-08-13
Tor 0.4.4.4-rc is the first release candidate in its series. It fixes
several bugs in previous versions, including some that caused annoying
behavior for relay and bridge operators.
o Minor features (security):
- Channels using obsolete versions of the Tor link protocol are no
longer allowed to circumvent address-canonicity checks. (This is
only a minor issue, since such channels have no way to set ed25519
keys, and therefore should always be rejected for circuits that
specify ed25519 identities.) Closes ticket 40081.
o Minor features (defense in depth):
- Wipe more data from connection address fields before returning
them to the memory heap. Closes ticket 6198.
o Minor bugfixes (correctness, buffers):
- Fix a correctness bug that could cause an assertion failure if we
ever tried using the buf_move_all() function with an empty input
buffer. As far as we know, no released versions of Tor do this.
Fixes bug 40076; bugfix on 0.3.3.1-alpha.
o Minor bugfixes (linux seccomp2 sandbox):
- Fix startup crash with seccomp sandbox enabled when tor tries to
open the data directory. Patch from Daniel Pinto. Fixes bug 40072;
bugfix on 0.4.4.3-alpha-dev.
o Minor bugfixes (onion service v3):
- Remove a BUG() warning that could trigger in certain unlikely
edge-cases. Fixes bug 34086; bugfix on 0.3.2.1-alpha.
o Minor bugfixes (rate limiting, bridges, pluggable transports):
- On a bridge, treat all connections from an ExtORPort as remote by
default for the purposes of rate-limiting. Previously, bridges
would treat the connection as local unless they explicitly
received a "USERADDR" command. ExtORPort connections still count
as local if there is a USERADDR command with an explicit local
address. Fixes bug 33747; bugfix on 0.2.5.1-alpha.
o Minor bugfixes (relay, self-testing):
- When starting up as a relay, if we haven't been able to verify
that we're reachable, only launch reachability tests at most once
a minute. Previously, we had been launching tests up to once a
second, which was needlessly noisy. Fixes bug 40083; bugfix
on 0.2.8.1-alpha.
o Minor bugfixes (testing):
- When running the subsystem order check, use the Python binary
configured with the PYTHON environment variable. Fixes bug 40095;
bugfix on 0.4.4.1-alpha.
o Minor bugfixes (windows):
- Fix a bug that prevented Tor from starting if its log file grew
above 2GB. Fixes bug 31036; bugfix on 0.2.1.8-alpha.
