Changes in version 0.2.6.11 - 2017-03-??
|
||||
Tor 0.2.6.11 backports a number of security fixes from later Tor
|
||||
releases. Anybody running Tor 0.2.6.10 or earlier should upgrade to
|
||||
this release, if for some reason they cannot upgrade to a later
|
||||
release series.
|
||||
|
||||
Note that support for Tor 0.2.6.x is ending next year: we will not issue
|
||||
any fixes for the Tor 0.2.6.x series after 1 August 2017. If you need
|
||||
a Tor release series with longer-term support, we recommend Tor 0.2.9.x.
|
||||
|
||||
o Directory authority changes (backport from 0.2.8.5-rc):
|
||||
- Urras is no longer a directory authority. Closes ticket 19271.
|
||||
|
||||
o Directory authority changes (backport from 0.2.9.2-alpha):
|
||||
- The "Tonga" bridge authority has been retired; the new bridge
|
||||
authority is "Bifroest". Closes tickets 19728 and 19690.
|
||||
|
||||
o Directory authority key updates (backport from 0.2.8.1-alpha):
|
||||
- Update the V3 identity key for the dannenberg directory authority:
|
||||
it was changed on 18 November 2015. Closes task 17906. Patch
|
||||
by "teor".
|
||||
|
||||
o Major bugfixes (dns proxy mode, crash, backport from 0.2.8.2-alpha):
|
||||
- Avoid crashing when running as a DNS proxy. Fixes bug 16248;
|
||||
bugfix on 0.2.0.1-alpha. Patch from "cypherpunks".
|
||||
|
||||
o Minor features (bug-resistance, backport from 0.2.8.2-alpha):
|
||||
- Make Tor survive errors involving connections without a
|
||||
corresponding event object. Previously we'd fail with an
|
||||
assertion; now we produce a log message. Related to bug 16248.
|
||||
|
||||
o Major bugfixes (security, correctness, backport from 0.2.7.4-rc):
|
||||
- Fix an error that could cause us to read 4 bytes before the
|
||||
beginning of an openssl string. This bug could be used to cause
|
||||
Tor to crash on systems with unusual malloc implementations, or
|
||||
systems with unusual hardening installed. Fixes bug 17404; bugfix
|
||||
on 0.2.3.6-alpha.
|
||||
|
||||
o Major bugfixes (guard selection, backport from 0.2.7.6):
|
||||
- Actually look at the Guard flag when selecting a new directory
|
||||
guard. When we implemented the directory guard design, we
|
||||
accidentally started treating all relays as if they have the Guard
|
||||
flag during guard selection, leading to weaker anonymity and worse
|
||||
performance. Fixes bug 17772; bugfix on 0.2.4.8-alpha. Discovered
|
||||
by Mohsen Imani.
|
||||
|
||||
o Minor bugfixes (compilation, backport from 0.2.7.6)
|
||||
- Fix a compilation warning with Clang 3.6: Do not check the
|
||||
presence of an address which can never be NULL. Fixes bug 17781.
|
||||
|
||||
o Minor features (geoip):
|
||||
- Update geoip and geoip6 to the February 8 2017 Maxmind GeoLite2
|
||||
Country database.
|
||||
|
||||
o Minor features (security, memory erasure, backport from 0.2.8.1-alpha):
|
||||
- Make memwipe() do nothing when passed a NULL pointer or buffer of
|
||||
zero size. Check size argument to memwipe() for underflow. Fixes
|
||||
bug 18089; bugfix on 0.2.3.25 and 0.2.4.6-alpha. Reported by "gk",
|
||||
patch by "teor".
|
||||
|
||||
o Major bugfixes (security, pointers, backport from 0.2.8.2-alpha):
|
||||
- Avoid a difficult-to-trigger heap corruption attack when extending
|
||||
a smartlist to contain over 16GB of pointers. Fixes bug 18162;
|
||||
bugfix on 0.1.1.11-alpha, which fixed a related bug incompletely.
|
||||
Reported by Guido Vranken.
|
||||
|
||||
o Major bugfixes (security, client, DNS proxy, backport from 0.2.8.3-alpha):
|
||||
- Stop a crash that could occur when a client running with DNSPort
|
||||
received a query with multiple address types, and the first
|
||||
address type was not supported. Found and fixed by Scott Dial.
|
||||
Fixes bug 18710; bugfix on 0.2.5.4-alpha.
|
||||
|
||||
o Major features (security fixes, backport from 0.2.9.4-alpha):
|
||||
- Prevent a class of security bugs caused by treating the contents
|
||||
of a buffer chunk as if they were a NUL-terminated string. At
|
||||
least one such bug seems to be present in all currently used
|
||||
versions of Tor, and would allow an attacker to remotely crash
|
||||
most Tor instances, especially those compiled with extra compiler
|
||||
hardening. With this defense in place, such bugs can't crash Tor,
|
||||
though we should still fix them as they occur. Closes ticket
|
||||
20384 (TROVE-2016-10-001).
|
||||
|
||||
o Major bugfixes (parsing, security, backport from 0.2.9.8):
|
||||
- Fix a bug in parsing that could cause clients to read a single
|
||||
byte past the end of an allocated region. This bug could be used
|
||||
to cause hardened clients (built with --enable-expensive-hardening)
|
||||
to crash if they tried to visit a hostile hidden service. Non-
|
||||
hardened clients are only affected depending on the details of
|
||||
their platform's memory allocator. Fixes bug 21018; bugfix on
|
||||
0.2.0.8-alpha. Found by using libFuzzer. Also tracked as TROVE-
|
||||
2016-12-002 and as CVE-2016-1254.
|
||||
|
||||
o Major bugfixes (key management, backport from 0.2.8.3-alpha):
|
||||
- If OpenSSL fails to generate an RSA key, do not retain a dangling
|
||||
pointer to the previous (uninitialized) key value. The impact here
|
||||
should be limited to a difficult-to-trigger crash, if OpenSSL is
|
||||
running an engine that makes key generation failures possible, or
|
||||
if OpenSSL runs out of memory. Fixes bug 19152; bugfix on
|
||||
0.2.1.10-alpha. Found by Yuan Jochen Kang, Suman Jana, and
|
||||
Baishakhi Ray.
|
||||
|
||||
o Major bugfixes (parsing, also in 0.3.0.4-rc):
|
||||
- Fix an integer underflow bug when comparing malformed Tor versions.
|
||||
This bug is harmless, except when Tor has been built with
|
||||
--enable-expensive-hardening, which would turn it into a crash;
|
||||
or on Tor 0.2.9.1-alpha through Tor 0.2.9.8, which were built with
|
||||
-ftrapv by default.
|
||||
Part of TROVE-2017-001. Fixes bug 21278; bugfix on
|
||||
0.0.8pre1. Found by OSS-Fuzz.

||||
|
||||
|
||||
Changes in version 0.2.6.10 - 2015-07-12
|
||||
Tor version 0.2.6.10 fixes some significant stability and hidden
|
||||
service client bugs, bulletproofs the cryptography init process, and
