This is a security regression; all clients running earlier + versions of 0.3.0.x or 0.3.1.x should upgrade to 0.3.0.9 or + 0.3.1.4-alpha. + + This release also backports several other bugfixes from the 0.3.1.x + series. + + o Major bugfixes (path selection, security, backport from 0.3.1.4-alpha): + - When choosing which guard to use for a circuit, avoid the exit's + family along with the exit itself. Previously, the new guard + selection logic avoided the exit, but did not consider its family. + Fixes bug 22753; bugfix on 0.3.0.1-alpha. Tracked as TROVE-2016- + 006 and CVE-2017-0377. + + o Major bugfixes (entry guards, backport from 0.3.1.1-alpha): + - Don't block bootstrapping when a primary bridge is offline and we + can't get its descriptor. Fixes bug 22325; fixes one case of bug + 21969; bugfix on 0.3.0.3-alpha. + + o Major bugfixes (entry guards, backport from 0.3.1.4-alpha): + - When starting with an old consensus, do not add new entry guards + unless the consensus is "reasonably live" (under 1 day old). Fixes + one root cause of bug 22400; bugfix on 0.3.0.1-alpha. + + o Minor features (geoip): + - Update geoip and geoip6 to the June 8 2017 Maxmind GeoLite2 + Country database. + + o Minor bugfixes (voting consistency, backport from 0.3.1.1-alpha): + - Reject version numbers with non-numeric prefixes (such as +, -, or + whitespace). Disallowing whitespace prevents differential version + parsing between POSIX-based and Windows platforms. Fixes bug 21507 + and part of 21508; bugfix on 0.0.8pre1. + + o Minor bugfixes (linux seccomp2 sandbox, backport from 0.3.1.4-alpha): + - Permit the fchmod system call, to avoid crashing on startup when + starting with the seccomp2 sandbox and an unexpected set of + permissions on the data directory or its contents. Fixes bug + 22516; bugfix on 0.2.5.4-alpha. + + o Minor bugfixes (defensive programming, backport from 0.3.1.4-alpha): + - Fix a memset() off the end of an array when packing cells. This + bug should be harmless in practice, since the corrupted bytes are + still in the same structure, and are always padding bytes, + ignored, or immediately overwritten, depending on compiler + behavior. Nevertheless, because the memset()'s purpose is to make + sure that any other cell-handling bugs can't expose bytes to the + network, we need to fix it. Fixes bug 22737; bugfix on + 0.2.4.11-alpha. Fixes CID 1401591. + + Changes in version 0.3.0.8 - 2017-06-08 Tor 0.3.0.8 fixes a pair of bugs that would allow an attacker to remotely crash a hidden service with an assertion failure. Anyone |
