  • Major bugfixes:
  • · Avoid an assertion failure when reloading a configuration withTrackExitHosts changes. Found and fixed by 'laruldan'. Fixes bug3923; bugfix on 0.2.2.25-alpha.

  • Minor features (security):
  • · Check for replays of the public-key encrypted portion of anINTRODUCE1 cell, in addition to the current check for replays ofthe g^x value. This prevents a possible class of active attacksby an attacker who controls both an introduction point and arendezvous point, and who uses the malleability of AES-CTR toalter the encrypted g^x portion of the INTRODUCE1 cell. We thinkthat these attacks are infeasible (requiring the attacker to sendon the order of zettabytes of altered cells in a short interval),but we'd rather block them off in case there are any classes ofthis attack that we missed. Reported by Willem Pinckaers.

  • Minor features:
  • · Adjust the expiration time on our SSL session certificates tobetter match SSL certs seen in the wild. Resolves ticket 4014.
  • · Change the default required uptime for a relay to be accepted asa HSDir (hidden service directory) from 24 hours to 25 hours.Improves on 0.2.0.10-alpha; resolves ticket 2649.
  • · Add a VoteOnHidServDirectoriesV2 config option to allow directoryauthorities to abstain from voting on assignment of the HSDirconsensus flag. Related to bug 2649.
  • · Update to the September 6 2011 Maxmind GeoLite Country database.

  • Minor bugfixes (documentation and log messages):
  • · Correct the man page to explain that HashedControlPassword andCookieAuthentication can both be set, in which case either methodis sufficient to authenticate to Tor. Bugfix on 0.2.0.7-alpha,when we decided to allow these config options to both be set. Issueraised by bug 3898.
  • · Demote the 'replay detected' log message emitted when a hiddenservice receives the same Diffie-Hellman public key in two differentINTRODUCE2 cells to info level. A normal Tor client can cause thatlog message during its normal operation. Bugfix on 0.2.1.6-alpha;fixes part of bug 2442.
  • · Demote the 'INTRODUCE2 cell is too {old,new}' log message to infolevel. There is nothing that a hidden service's operator can doto fix its clients' clocks. Bugfix on 0.2.1.6-alpha; fixes partof bug 2442.
  • · Clarify a log message specifying the characters permitted inHiddenServiceAuthorizeClient client names. Previously, the logmessage said that "[A-Za-z0-9+-_]" were permitted; that could havegiven the impression that every ASCII character between "+" and "_"was permitted. Now we say "[A-Za-z0-9+_-]". Bugfix on 0.2.1.5-alpha.

  • Build fixes:
  • · Provide a substitute implementation of lround() for MSVC, whichapparently lacks it. Patch from Gisle Vanem.
  • · Clean up some code issues that prevented Tor from building on olderBSDs. Fixes bug 3894; reported by "grarpamp".
  • · Search for a platform-specific version of "ar" when cross-compiling.Should fix builds on iOS. Resolves bug 3909, found by Marco Bonetti.
Pros
