|

Tor 0.3.1.10 backports a number of bugfixes, including important fixes for
|
||||
security issues.
|
||||
|
||||
BLURB HERE.
|
||||
It includes an important security fix for a remote crash attack
|
||||
against directory authorities, tracked as TROVE-2018-001.
|
||||
|
||||
This release also backports our new system for improved resistance to
|
||||
denial-of-service attacks against relays.
|
||||
|
||||
This release also fixes several minor bugs and annoyances from
|
||||
earlier releases.
|
||||
|
||||
All directory authorities should upgrade to one of the versions
|
||||
released today. All relays not already running Tor 0.3.3.2-alpha or
|
||||
later should upgrade to one of the versions released today.
|
||||
|
||||
Please note: according to our release calendar, Tor 0.3.1 will no
|
||||
longer be supported after 1 July 2018. If you will be running Tor
|
||||
after that date, you should make sure to plan to upgrade to the latest
|
||||
stable version, or downgrade to 0.2.9 (which will receive long-term
|
||||
support).
|
||||
|
||||
o Major bugfixes (denial-of-service, directory authority, backport from 0.3.3.3-alpha):
|
||||
- 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 Major features (denial-of-service mitigation, backport from 0.3.3.2-alpha):

|

|

o Minor bugfixes (denial-of-service, backport from 0.3.3.3-alpha):
|
||||
- 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 (directory cache, backport from 0.3.2.5-alpha):
|

- Recover better from empty or corrupt files in the consensus cache

directory. Fixes bug 24099; bugfix on 0.3.1.1-alpha.

o Code simplification and refactoring (backport from 0.3.3.3-alpha):

- Update the "rust dependencies" submodule to be a project-level

repository, rather than a user repository. Closes ticket 25323.
