Closes ticket 25378. -Changes in version 0.3.3.3-alpha - 2018-03-03 - Tor 0.3.3.3-alpha is the third alpha release for the 0.3.3.x series. - It includes an important security fix for a remote crash attack - against directory authorities tracked as TROVE-2018-001. - - Additionally, with this release, we are upgrading the severity of a - bug fixed in 0.3.3.2-alpha. Bug 24700, which was fixed in - 0.3.3.2-alpha, can be remotely triggered in order to crash relays with - a use-after-free pattern. As such, we are now tracking that bug as - TROVE-2018-002 and CVE-2018-0491. This bug affected versions - 0.3.2.1-alpha through 0.3.2.9, as well as 0.3.3.1-alpha. - - This release also fixes several minor bugs and annoyances from - earlier releases. - - Relays running 0.3.2.x should upgrade to one of the versions released - today, for the fix to TROVE-2018-002. Directory authorities should - also upgrade. (Relays on earlier versions might want to update too for - the DoS mitigations.) - - o Major bugfixes (denial-of-service, directory authority): - - Fix a protocol-list handling bug that could be used to remotely crash - directory authorities with a null-pointer exception. Fixes bug 25074; - bugfix on 0.2.9.4-alpha. Also tracked as TROVE-2018-001 and - CVE-2018-0490. - - o Minor features (compatibility, OpenSSL): - - Tor will now support TLS1.3 once OpenSSL 1.1.1 is released. - Previous versions of Tor would not have worked with OpenSSL 1.1.1, - since they neither disabled TLS 1.3 nor enabled any of the - ciphersuites it requires. Now we enable the TLS 1.3 ciphersuites. - Closes ticket 24978. - - o Minor features (logging): - - Clarify the log messages produced when getrandom() or a related - entropy-generation mechanism gives an error. Closes ticket 25120. - - o Minor features (testing): - - Add a "make test-rust" target to run the rust tests only. Closes - ticket 25071. - - o Minor bugfixes (denial-of-service): - - Fix a possible crash on malformed consensus. If a consensus had - contained an unparseable protocol line, it could have made clients - and relays crash with a null-pointer exception. To exploit this - issue, however, an attacker would need to be able to subvert the - directory authority system. Fixes bug 25251; bugfix on - 0.2.9.4-alpha. Also tracked as TROVE-2018-004. - - o Minor bugfixes (DoS mitigation): - - Add extra safety checks when refilling the circuit creation bucket - to ensure we never set a value above the allowed maximum burst. - Fixes bug 25202; bugfix on 0.3.3.2-alpha. - - When a new consensus arrives, don't update our DoS-mitigation - parameters if we aren't a public relay. Fixes bug 25223; bugfix - on 0.3.3.2-alpha. - - o Minor bugfixes (man page, SocksPort): - - Remove dead code from the old "SocksSocket" option, and rename - SocksSocketsGroupWritable to UnixSocksGroupWritable. The old option - still works, but is deprecated. Fixes bug 24343; bugfix on 0.2.6.3. - - o Minor bugfixes (performance): - - Reduce the number of circuits that will be opened at once during - the circuit build timeout phase. This is done by increasing the - idle timeout to 3 minutes, and lowering the maximum number of - concurrent learning circuits to 10. Fixes bug 24769; bugfix - on 0.3.1.1-alpha. - - o Minor bugfixes (spec conformance): - - Forbid "-0" as a protocol version.

Fixes part of bug 25249; - bugfix on 0.2.9.4-alpha. - - o Minor bugfixes (spec conformance, rust): - - Resolve a denial-of-service issue caused by an infinite loop in - the rust protover code.
