    Hello! I released Tor 0.2.4.26 and 0.2.5.11 last week. This is the formal announcement.

    (Per usual practice with non-critical stable releases, I've delayed
    the tor-announce announcement to give distributions have a chance to
    make packages. If you are a packager and you didn't notice that,
    please let me know and I'll put you on the list of people I notify
    extra-early about new releases.)

    Tor 0.2.4 and 0.2.5 are stable release series. Going forward, they will continue to only receive patches for really serious issues.

    You can get the source code for Tor 0.2.4.26 and 0.2.5.11 from the download page, or at https://dist.torproject.org/. If you're running TorBrowser 4.0.5, you already have Tor 0.2.5.11. Remember to check the signatures!

    The changelogs follow below...


    Tor 0.2.4.26 includes an updated list of directory authorities. It also backports a couple of stability and security bugfixes from 0.2.5 and beyond.

    Changes in version 0.2.4.26 - 2015-03-17

    • Directory authority changes:
      • Remove turtles as a directory authority.
      • Add longclaw as a new (v3) directory authority. This implements ticket 13296. This keeps the directory authority count at 9.
      • The directory authority Faravahar has a new IP address. This closes ticket 14487.
    • Major bugfixes (exit node stability, also in 0.2.6.3-alpha):
      • Fix an assertion failure that could occur under high DNS load. Fixes bug 14129; bugfix on Tor 0.0.7rc1. Found by "jowr"; diagnosed and fixed by "cypherpunks".
    • Major bugfixes (relay, stability, possible security, also in 0.2.6.4-rc):
      • Fix a bug that could lead to a relay crashing with an assertion failure if a buffer of exactly the wrong layout was passed to buf_pullup() at exactly the wrong time. Fixes bug 15083; bugfix on 0.2.0.10-alpha. Patch from 'cypherpunks'.
      • Do not assert if the 'data' pointer on a buffer is advanced to the very end of the buffer; log a BUG message instead. Only assert if it is past that point. Fixes bug 15083; bugfix on 0.2.0.10-alpha.
    • Minor features (geoip):
      • Update geoip to the March 3 2015 Maxmind GeoLite2 Country database.
      • Update geoip6 to the March 3 2015 Maxmind GeoLite2 Country database.

    • Tor 0.2.5.11 is the second stable release in the 0.2.5 series.

      It backports several bugfixes from the 0.2.6 branch, including a couple of medium-level security fixes for relays and exit nodes. It also updates the list of directory authorities.

      Changes in version 0.2.5.11 - 2015-03-17

        • The directory authority Faravahar has a new IP address. This closes ticket 14487.
      • Major bugfixes (crash, OSX, security):
        • Fix a remote denial-of-service opportunity caused by a bug in OSX's _strlcat_chk() function. Fixes bug 15205; bug first appeared in OSX 10.9.
      • Major bugfixes (relay, stability, possible security):
        • Fix a bug that could lead to a relay crashing with an assertion failure if a buffer of exactly the wrong layout was passed to buf_pullup() at exactly the wrong time. Fixes bug 15083; bugfix on 0.2.0.10-alpha. Patch from 'cypherpunks'.
        • Do not assert if the 'data' pointer on a buffer is advanced to the very end of the buffer; log a BUG message instead. Only assert if it is past that point. Fixes bug 15083; bugfix on 0.2.0.10-alpha.
      • Major bugfixes (exit node stability):
        • Fix an assertion failure that could occur under high DNS load. Fixes bug 14129; bugfix on Tor 0.0.7rc1. Found by "jowr"; diagnosed and fixed by "cypherpunks".
      • Major bugfixes (Linux seccomp2 sandbox):
        • Upon receiving sighup with the seccomp2 sandbox enabled, do not crash during attempts to call wait4. Fixes bug 15088; bugfix on 0.2.5.1-alpha. Patch from "sanic".
      • Minor features (controller):
        • New "GETINFO bw-event-cache" to get information about recent bandwidth events. Closes ticket 14128. Useful for controllers to get recent bandwidth history after the fix for ticket 13988.
      • Minor features (geoip):
        • Update geoip to the March 3 2015 Maxmind GeoLite2 Country database.
        • Update geoip6 to the March 3 2015 Maxmind GeoLite2 Country database.
      • Minor bugfixes (client, automapping):
        • Avoid crashing on torrc lines for VirtualAddrNetworkIPv[4|6] when no value follows the option. Fixes bug 14142; bugfix on 0.2.4.7-alpha. Patch by "teor".
        • Fix a memory leak when using AutomapHostsOnResolve. Fixes bug 14195; bugfix on 0.1.0.1-rc.
      • Minor bugfixes (compilation):
        • Build without warnings with the stock OpenSSL srtp.h header, which has a duplicate declaration of SSL_get_selected_srtp_profile(). Fixes bug 14220; this is OpenSSL's bug, not ours.
      • Minor bugfixes (directory authority):
        • Allow directory authorities to fetch more data from one another if they find themselves missing lots of votes. Previously, they had been bumping against the 10 MB queued data limit. Fixes bug 14261; bugfix on 0.1.2.5-alpha.
        • Enlarge the buffer to read bwauth generated files to avoid an issue when parsing the file in dirserv_read_measured_bandwidths(). Fixes bug 14125; bugfix on 0.2.2.1-alpha.
      • Minor bugfixes (statistics):
        • Increase period over which bandwidth observations are aggregated from 15 minutes to 4 hours. Fixes bug 13988; bugfix on 0.0.8pre1.
      • Minor bugfixes (preventative security, C safety):
        • When reading a hexadecimal, base-32, or base-64 encoded value from a string, always overwrite the whole output buffer. This prevents some bugs where we would look at (but fortunately, not reveal) uninitialized memory on the stack. Fixes bug 14013; bugfix on all versions of Tor.
