Changes in version 0.3.5.8 - 2019-02-21
Tor 0.3.5.8 backports serveral fixes from later releases, including fixes
for an annoying SOCKS-parsing bug that affected users in earlier 0.3.5.x
releases.
It also includes a fix for a medium-severity security bug affecting Tor
0.3.2.1-alpha and later. All Tor instances running an affected release
should upgrade to 0.3.3.12, 0.3.4.11, 0.3.5.8, or 0.4.0.2-alpha.
o Major bugfixes (cell scheduler, KIST, security):
- Make KIST consider the outbuf length when computing what it can
put in the outbuf. Previously, KIST acted as though the outbuf
were empty, which could lead to the outbuf becoming too full. It
is possible that an attacker could exploit this bug to cause a Tor
client or relay to run out of memory and crash. Fixes bug 29168;
bugfix on 0.3.2.1-alpha. This issue is also being tracked as
TROVE-2019-001 and CVE-2019-8955.
o Major bugfixes (networking, backport from 0.4.0.2-alpha):
- Gracefully handle empty username/password fields in SOCKS5
username/password auth messsage and allow SOCKS5 handshake to
continue. Previously, we had rejected these handshakes, breaking
certain applications. Fixes bug 29175; bugfix on 0.3.5.1-alpha.
o Minor features (compilation, backport from 0.4.0.2-alpha):
- Compile correctly when OpenSSL is built with engine support
disabled, or with deprecated APIs disabled. Closes ticket 29026.
Patches from "Mangix".
o Minor features (geoip):
- Update geoip and geoip6 to the February 5 2019 Maxmind GeoLite2
Country database. Closes ticket 29478.
o Minor features (testing, backport from 0.4.0.2-alpha):
- Treat all unexpected ERR and BUG messages as test failures. Closes
ticket 28668.
o Minor bugfixes (onion service v3, client, backport from 0.4.0.1-alpha):
- Stop logging a "BUG()" warning and stacktrace when we find a SOCKS
connection waiting for a descriptor that we actually have in the
cache. It turns out that this can actually happen, though it is
rare. Now, tor will recover and retry the descriptor. Fixes bug
28669; bugfix on 0.3.2.4-alpha.
o Minor bugfixes (IPv6, backport from 0.4.0.1-alpha):
- Fix tor_ersatz_socketpair on IPv6-only systems. Previously, the
IPv6 socket was bound using an address family of AF_INET instead
of AF_INET6. Fixes bug 28995; bugfix on 0.3.5.1-alpha. Patch from
Kris Katterjohn.
o Minor bugfixes (build, compatibility, rust, backport from 0.4.0.2-alpha):
- Update Cargo.lock file to match the version made by the latest
version of Rust, so that "make distcheck" will pass again. Fixes
bug 29244; bugfix on 0.3.3.4-alpha.
o Minor bugfixes (client, clock skew, backport from 0.4.0.1-alpha):
- Select guards even if the consensus has expired, as long as the
consensus is still reasonably live. Fixes bug 24661; bugfix
on 0.3.0.1-alpha.
o Minor bugfixes (compilation, backport from 0.4.0.1-alpha):
- Compile correctly on OpenBSD; previously, we were missing some
headers required in order to detect it properly. Fixes bug 28938;
bugfix on 0.3.5.1-alpha. Patch from Kris Katterjohn.
o Minor bugfixes (documentation, backport from 0.4.0.2-alpha):
- Describe the contents of the v3 onion service client authorization
files correctly: They hold public keys, not private keys. Fixes
bug 28979; bugfix on 0.3.5.1-alpha. Spotted by "Felixix".
o Minor bugfixes (logging, backport from 0.4.0.1-alpha):
- Rework rep_hist_log_link_protocol_counts() to iterate through all
link protocol versions when logging incoming/outgoing connection
counts. Tor no longer skips version 5, and we won't have to
remember to update this function when new link protocol version is
developed. Fixes bug 28920; bugfix on 0.2.6.10.
o Minor bugfixes (logging, backport from 0.4.0.2-alpha):
- Log more information at "warning" level when unable to read a
private key; log more information at "info" level when unable to
read a public key. We had warnings here before, but they were lost
during our NSS work. Fixes bug 29042; bugfix on 0.3.5.1-alpha.
o Minor bugfixes (misc, backport from 0.4.0.2-alpha):
- The amount of total available physical memory is now determined
using the sysctl identifier HW_PHYSMEM (rather than HW_USERMEM)
when it is defined and a 64-bit variant is not available. Fixes
bug 28981; bugfix on 0.2.5.4-alpha. Patch from Kris Katterjohn.
o Minor bugfixes (onion services, backport from 0.4.0.2-alpha):
- Avoid crashing if ClientOnionAuthDir (incorrectly) contains more
than one private key for a hidden service. Fixes bug 29040; bugfix
on 0.3.5.1-alpha.
- In hs_cache_store_as_client() log an HSDesc we failed to parse at
"debug" level. Tor used to log it as a warning, which caused very
long log lines to appear for some users. Fixes bug 29135; bugfix
on 0.3.2.1-alpha.
- Stop logging "Tried to establish rendezvous on non-OR circuit..."
as a warning. Instead, log it as a protocol warning, because there
is nothing that relay operators can do to fix it. Fixes bug 29029;
bugfix on 0.2.5.7-rc.
o Minor bugfixes (tests, directory clients, backport from 0.4.0.1-alpha):
- Mark outdated dirservers when Tor only has a reasonably live
consensus. Fixes bug 28569; bugfix on 0.3.2.5-alpha.
o Minor bugfixes (tests, backport from 0.4.0.2-alpha):
- Detect and suppress "bug" warnings from the util/time test on
Windows. Fixes bug 29161; bugfix on 0.2.9.3-alpha.
- Do not log an error-level message if we fail to find an IPv6
network interface from the unit tests. Fixes bug 29160; bugfix
on 0.2.7.3-rc.
o Minor bugfixes (usability, backport from 0.4.0.1-alpha):
- Stop saying "Your Guard ..." in pathbias_measure_{use,close}_rate().
Some users took this phrasing to mean that the mentioned guard was
under their control or responsibility, which it is not. Fixes bug
28895; bugfix on Tor 0.3.0.1-alpha.
Changes in version 0.3.4.11 - 2019-02-21
Tor 0.3.4.11 is the third stable release in its series. It includes
a fix for a medium-severity security bug affecting Tor 0.3.2.1-alpha and
later. All Tor instances running an affected release should upgrade to
0.3.3.12, 0.3.4.11, 0.3.5.8, or 0.4.0.2-alpha.
o Major bugfixes (cell scheduler, KIST, security):
- Make KIST consider the outbuf length when computing what it can
put in the outbuf. Previously, KIST acted as though the outbuf
were empty, which could lead to the outbuf becoming too full. It
is possible that an attacker could exploit this bug to cause a Tor
client or relay to run out of memory and crash. Fixes bug 29168;
bugfix on 0.3.2.1-alpha. This issue is also being tracked as
TROVE-2019-001 and CVE-2019-8955.
o Minor features (geoip):
- Update geoip and geoip6 to the February 5 2019 Maxmind GeoLite2

bugfix on 0.2.5.7-rc.
Changes in version 0.3.3.12 - 2019-02-21
Tor 0.3.3.12 fixes a medium-severity security bug affecting Tor
0.3.2.1-alpha and later. All Tor instances running an affected release
should upgrade to 0.3.3.12, 0.3.4.11, 0.3.5.8, or 0.4.0.2-alpha.
This release marks the end of support for the Tor 0.3.3.x series. We
recommend that users 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 (cell scheduler, KIST, security):
- Make KIST consider the outbuf length when computing what it can
put in the outbuf. Previously, KIST acted as though the outbuf
were empty, which could lead to the outbuf becoming too full. It
is possible that an attacker could exploit this bug to cause a Tor

bugfix on 0.2.5.7-rc.
Changes in version 0.4.0.2-alpha - 2019-02-21
Tor 0.4.0.2-alpha is the second alpha in its series; it fixes several
bugs from earlier versions, including several that had broken
backward compatibility.
It also includes a fix for a medium-severity security bug affecting Tor
0.3.2.1-alpha and later. All Tor instances running an affected release
should upgrade to 0.3.3.12, 0.3.4.11, 0.3.5.8, or 0.4.0.2-alpha.
o Major bugfixes (cell scheduler, KIST, security):
- Make KIST consider the outbuf length when computing what it can
put in the outbuf. Previously, KIST acted as though the outbuf
were empty, which could lead to the outbuf becoming too full. It
is possible that an attacker could exploit this bug to cause a Tor
client or relay to run out of memory and crash. Fixes bug 29168;

username/password auth messsage and allow SOCKS5 handshake to
continue. Previously, we had rejected these handshakes, breaking
certain applications. Fixes bug 29175; bugfix on 0.3.5.1-alpha.
o Major bugfixes (windows, startup):
- When reading a consensus file from disk, detect whether it was
written in text mode, and re-read it in text mode if so. Always
write consensus files in binary mode so that we can map them into
memory later. Previously, we had written in text mode, which
confused us when we tried to map the file on windows. Fixes bug
28614; bugfix on 0.4.0.1-alpha.
o Minor features (compilation):
- Compile correctly when OpenSSL is built with engine support
disabled, or with deprecated APIs disabled. Closes ticket 29026.
Patches from "Mangix".
o Minor features (developer tooling):
- Check that bugfix versions in changes files look like Tor versions
from the versions spec. Warn when bugfixes claim to be on a future
release. Closes ticket 27761.
- Provide a git pre-commit hook that disallows commiting if we have
any failures in our code and changelog formatting checks. It is
now available in scripts/maint/pre-commit.git-hook. Implements
feature 28976.
o Minor features (directory authority):
- When a directory authority is using a bandwidth file to obtain
bandwidth values, include the digest of that file in the vote.
Closes ticket 26698.
o Minor features (geoip):
- Update geoip and geoip6 to the February 5 2019 Maxmind GeoLite2
Country database. Closes ticket 29478.
o Minor features (testing):
- Treat all unexpected ERR and BUG messages as test failures. Closes
ticket 28668.
o Minor bugfixes (build, compatibility, rust):
- Update Cargo.lock file to match the version made by the latest
version of Rust, so that "make distcheck" will pass again. Fixes
bug 29244; bugfix on 0.3.3.4-alpha.
o Minor bugfixes (compilation):
- Fix compilation warnings in test_circuitpadding.c. Fixes bug
29169; bugfix on 0.4.0.1-alpha.
- Silence a compiler warning in test-memwipe.c on OpenBSD. Fixes bug
29145; bugfix on 0.2.9.3-alpha. Patch from Kris Katterjohn.
o Minor bugfixes (documentation):
- Describe the contents of the v3 onion service client authorization
files correctly: They hold public keys, not private keys. Fixes
bug 28979; bugfix on 0.3.5.1-alpha. Spotted by "Felixix".
o Minor bugfixes (linux seccomp sandbox):
- Fix startup crash when experimental sandbox support is enabled.
Fixes bug 29150; bugfix on 0.4.0.1-alpha. Patch by Peter Gerber.
o Minor bugfixes (logging):
- Avoid logging that we are relaxing a circuit timeout when that
timeout is fixed. Fixes bug 28698; bugfix on 0.2.4.7-alpha.
- Log more information at "warning" level when unable to read a
private key; log more information at "info" level when unable to
read a public key. We had warnings here before, but they were lost
during our NSS work. Fixes bug 29042; bugfix on 0.3.5.1-alpha.
o Minor bugfixes (misc):

than one private key for a hidden service. Fixes bug 29040; bugfix
on 0.3.5.1-alpha.
- In hs_cache_store_as_client() log an HSDesc we failed to parse at
"debug" level. Tor used to log it as a warning, which caused very
long log lines to appear for some users. Fixes bug 29135; bugfix
on 0.3.2.1-alpha.
- Stop logging "Tried to establish rendezvous on non-OR circuit..."
as a warning. Instead, log it as a protocol warning, because there
is nothing that relay operators can do to fix it. Fixes bug 29029;
bugfix on 0.2.5.7-rc.
o Minor bugfixes (scheduler):
- When re-adding channels to the pending list, check the correct
channel's sched_heap_idx. This issue has had no effect in mainline
Tor, but could have led to bugs down the road in improved versions
of our circuit scheduling code. Fixes bug 29508; bugfix
on 0.3.2.10.
o Minor bugfixes (tests):
- Fix intermittent failures on an adaptive padding test. Fixes one
case of bug 29122; bugfix on 0.4.0.1-alpha.
- Disable an unstable circuit-padding test that was failing
intermittently because of an ill-defined small histogram. Such
histograms will be allowed again after 29298 is implemented. Fixes
a second case of bug 29122; bugfix on 0.4.0.1-alpha.
- Detect and suppress "bug" warnings from the util/time test on
Windows. Fixes bug 29161; bugfix on 0.2.9.3-alpha.
- Do not log an error-level message if we fail to find an IPv6
network interface from the unit tests. Fixes bug 29160; bugfix
on 0.2.7.3-rc.
o Documentation:
- In the manpage entry describing MapAddress torrc setting, use
example IP addresses from ranges specified for use in documentation
by RFC 5737. Resolves issue 28623.
o Removed features:
- Remove the old check-tor script. Resolves issue 29072.

should upgrade to 0.3.3.12, 0.3.4.11, 0.3.5.8, or 0.4.0.2-alpha.
This release marks the end of support for the Tor 0.3.3.x series. We
recommend that users 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.
