This approach can improve security on connections + where Tor's circuit handshake is stronger than the available TLS + connection security levels, but the tradeoff is more computational + load on guard relays. Implements proposal 221. Resolves ticket 9386. + - Make the number of entry guards configurable via a new + NumEntryGuards consensus parameter, and the number of directory + guards configurable via a new NumDirectoryGuards consensus + parameter. Implements ticket 12688. + + o Major bugfixes: + - Fix a bug in the bounds-checking in the 32-bit curve25519-donna + implementation that caused incorrect results on 32-bit + implementations when certain malformed inputs were used along with + a small class of private ntor keys. This bug does not currently + appear to allow an attacker to learn private keys or impersonate a + Tor server, but it could provide a means to distinguish 32-bit Tor + implementations from 64-bit Tor implementations. Fixes bug 12694; + bugfix on 0.2.4.8-alpha. Bug found by Robert Ransom; fix from + Adam Langley. + + o Minor bugfixes: + - Warn and drop the circuit if we receive an inbound 'relay early' + cell. Those used to be normal to receive on hidden service circuits + due to bug 1038, but the buggy Tor versions are long gone from + the network so we can afford to resume watching for them. Resolves + the rest of bug 1038; bugfix on 0.2.1.19. + - Correct a confusing error message when trying to extend a circuit + via the control protocol but we don't know a descriptor or + microdescriptor for one of the specified relays. Fixes bug 12718; + bugfix on 0.2.3.1-alpha. + - Avoid an illegal read from stack when initializing the TLS + module using a version of OpenSSL without all of the ciphers + used by the v2 link handshake. Fixes bug 12227; bugfix on + 0.2.4.8-alpha. Found by "starlight". + o Minor features: - Update geoip and geoip6 to the July 10 2014 Maxmind GeoLite2 Country database. diff --git a/changes/bug1038-3 b/changes/bug1038-3 deleted file mode 100644 index 5af4afa..0000000 --- a/changes/bug1038-3 +++ /dev/null @@ -1,6 +0,0 @@ - o Minor bugfixes: - - Warn and drop the circuit if we receive an inbound 'relay early' - cell.
