If you want to see more detailed descriptions of the changes in each development snapshot, see the ChangeLog file. +Changes in version 0.2.9.10 - 2017-03-01 + Tor 0.2.9.10 backports a security fix from later Tor release. It also + includes fixes for some major issues affecting directory authorities, + LibreSSL compatibility, and IPv6 correctness. + + The Tor 0.2.9.x release series is now marked as a long-term-support + series. We intend to backport security fixes to 0.2.9.x until at + least January of 2020. + + o Major bugfixes (directory authority, 0.3.0.3-alpha): + - During voting, when marking a relay as a probable sybil, do not + clear its BadExit flag: sybils can still be bad in other ways + too. (We still clear the other flags.) Fixes bug 21108; bugfix + on 0.2.0.13-alpha. + + o Major bugfixes (IPv6 Exits, backport from 0.3.0.3-alpha): + - Stop rejecting all IPv6 traffic on Exits whose exit policy rejects + any IPv6 addresses. Instead, only reject a port over IPv6 if the + exit policy rejects that port on more than an IPv6 /16 of + addresses. This bug was made worse by 17027 in 0.2.8.1-alpha, + which rejected a relay's own IPv6 address by default. Fixes bug + 21357; bugfix on commit 004f3f4e53 in 0.2.4.7-alpha. + + o Major bugfixes (parsing, also in 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 (directory authorities, also in 0.3.0.4-rc): + - Directory authorities now reject descriptors that claim to be + malformed versions of Tor. Helps prevent exploitation of + bug 21278. + - Reject version numbers with components that exceed INT32_MAX. + Otherwise 32-bit and 64-bit platforms would behave inconsistently. + Fixes bug 21450; bugfix on 0.0.8pre1. + + o Minor features (geoip): + - Update geoip and geoip6 to the February 8 2017 Maxmind GeoLite2 + Country database. + + o Minor features (portability, compilation, backport from 0.3.0.3-alpha): + - Autoconf now checks to determine if OpenSSL structures are opaque, + instead of explicitly checking for OpenSSL version numbers. Part + of ticket 21359. + - Support building with recent LibreSSL code that uses opaque + structures. Closes ticket 21359. + + o Minor bugfixes (code correctness, also in 0.3.0.4-rc): + - Repair a couple of (unreachable or harmless) cases of the risky + comparison-by-subtraction pattern that caused bug 21278. + + o Minor bugfixes (tor-resolve, backport from 0.3.0.3-alpha): + - The tor-resolve command line tool now rejects hostnames over 255 + characters in length. Previously, it would silently truncate them, + which could lead to bugs. Fixes bug 21280; bugfix on 0.0.9pre5. + Patch by "junglefowl". + + Changes in version 0.2.9.9 - 2017-01-23 Tor 0.2.9.9 fixes a denial-of-service bug where an attacker could cause relays and clients to crash, even if they were not built with
