+Changes in version 0.2.7.7 - 2017-03-03
+ Tor 0.2.7.7 backports a number of security fixes from later Tor
+ releases. Anybody running Tor 0.2.7.6 or earlier should upgrade to
+ this release, if for some reason they cannot upgrade to a later
+ release series.
+
+ Note that support for Tor 0.2.7.x is ending this year: we will not issue
+ any fixes for the Tor 0.2.7.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 (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 (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.
+ - 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 (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 (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 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, backported from 0.3.0.4-rc):
+ - Fix an integer underflow bug when comparing malformed Tor
+ versions. This bug could crash Tor when built with
+ --enable-expensive-hardening, or on Tor 0.2.9.1-alpha through Tor
+ 0.2.9.8, which were built with -ftrapv by default. In other cases
+ it was harmless. Part of TROVE-2017-001. Fixes bug 21278; bugfix
+ on 0.0.8pre1. Found by OSS-Fuzz.
+
+ 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 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 Minor features (geoip):
+ - Update geoip and geoip6 to the February 8 2017 Maxmind GeoLite2
+ Country database.
+
+
Changes in version 0.2.7.6 - 2015-12-10
