Changes in version 0.2.2 - 2014-06-XXX
* FIXES #9874 https://trac.torproject.org/projects/tor/ticket/9874
BridgeDB's email and HTTPS distributors were written in a manner
that makes them largely impossible to write unittests for. Since
the recent rewrite of BridgeDB's email distributor server backends
for version 0.2.1, BridgeDB email distributor is now testable and
has near 100% code coverage, see
* FIXES #12086 https://trac.torproject.org/projects/tor/ticket/12086
BridgeDB was found to accept incoming emails sent to any email
address whose local part included the word bridges, e.g. emails
sent to 'givemebridges@serious.ly' would be responded to as if
they were destined for BridgeDB's real email address.
- BridgeDB now strictly checks that the local part of the email
address that an incoming email was sent to (after removing plus
aliases, i.e. '+es_ES', '+fa', etc.) exactly matches BridgeDB
configured email address username.
- BridgeDB now checks that the domain name portion of the email
address that an incoming email was sent to either matches the
domain name portion of BridgeDB's configured email address, or
is a subdomain of that domain.
* FIXES #12089 https://trac.torproject.org/projects/tor/ticket/12089
There has been a bug for quite some time now where BridgeDB could
be used to email arbitrary email addresses (as long as these
addresses were ones which BridgeDB allows, i.e. Gmail or Yahoo
email addresses). This was due to BridgeDB not checking that the
email address used in the SMTP 'MAIL FROM:' command on an incoming
message matched the one used in that email's 'From:'
- BridgeDB now checks that the email addresses in the SMTP 'MAIL
FROM:' and the 'From:' header on that incoming email match, in
addition to the previous checks that the email address' domain
is in the set of allowed domains.
* FIXES #12090 https://trac.torproject.org/projects/tor/ticket/12090
BridgeDB has been replying with an empty email. I don't actually
know for sure if this one is fixed. Before deploying version
0.2.1, the continuous integration tests showed email responses
being correctly generated, and I was also able to receive
correctly formed email responses from BridgeDB on a local testing
instance on my laptop. It appears that this bug occurs only on the
deployment server at ponticum.torproject.org, possibly due to the
outdated Python version in Debian Wheezy. I have not been able to
reproduce this bug on any other machine.
* FIXES #12091 https://trac.torproject.org/projects/tor/ticket/12091
BridgeDB wasn't properly ignoring emails whose DKIM signature
verification header read "X-DKIM-Authentication-Results: dunno".
- Bridgedb now marks incoming emails which have a
"X-DKIM-Authentication-Results: dunno" header as invalid and
ignores them.
* FIXES #12147 https://trac.torproject.org/projects/tor/ticket/12147
If a user refreshed https://bridges.torproject.org/bridges after
successfully solving a CAPTCHA, BridgeDB would reply with a new
set of bridges for each page refresh. This was due to the use of
`getIterval()` in `IPBasedDistributor.getBridgesForIP()`.The
correct function to use is `getIntervalStart()`. This had been
noted in a "XXX FIXME" comment above the call for quite some time,
however, when the `bridgedb.schedule` (previously called
`bridgedb.Time`) module was revised to support CAPTCHA timeouts
(#11215), the call to `getInterval()` was mistakenly not replaced
with the correct function.
- BridgeDB CAPTCHAs must be solved within 10 minutes.
- Hashring rotation for bridges in BridgeDB HTTPS distributor
occurs every 3 hours. Refreshing the page with bridges on it
will return these same bridges for that time period, and
afterwards redirect back to the CAPTCHA page.
THANKS TO francisco on IRC and arma for reporting the bug.
And include the following general changes:
* FIXES an issue where, when verifying GnuPG signatures made by
BridgeDB's email distributor, GnuPG would error, saying, "invalid
armor header".
Changes in version 0.2.1 - 2014-05-16
* FIXES #5463 https://trac.torproject.org/projects/tor/ticket/5463
Emails sent from BridgeDB's email distributor should now be signed.
