+Changes in version 0.2.5.11 - 2015-03-17
|
|
|
+ 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.
|
|
|
+
|
|
|
+ o 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.
|
|
|
+
|
|
|
+ o 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.
|
|
|
+
|
|
|
+ o 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.
|
|
|
+
|
|
|
+ o 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".
|
|
|
+
|
|
|
+ o 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".
|
|
|
+
|
|
|
+ o 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.
|
|
|
+
|
|
|
+ o 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.
|
|
|
+
|
|
|
+ o 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.
|
|
|
+
|
|
|
+ o 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.
|
|
|
+
|
|
|
+ o 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.
|
|
|
+
|
|
|
+ o 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.
|
|
|
+
|
|
|
+ o 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.
