Gemfile: - Upgrade to Jekyll 3.x (3.0.1 tested). This brings several new features I want to use, most notably *collections* which allows us to add blog-like collections. I've converted the `_releases` and `_alerts` pages into collections, although their plugins are maintained to handle the Download and Active Alert features. - Upgrade to latest Kramdown. - Lock Less at 2.4.0. This prevents breaking our Less plugin. Jekyll 3.x provides native support for SCSS, so we may want to switch to that in time. - Lock HTML Proofer at 2.1.0. The most recent version was taking forever to check our pages (I never actually got it to complete). I'll look into it when I get more time. Makefile: - New `make clean` command. Jekyll 3.x by default attempts to do incremental rebuilds. The new `jekyll clean` command cleans up the metadata necessary for than so that a full build is performed, and this new `make clean` command is a wrapper around it so that we automatically do full rebuilds in the relevant cases. Note: our plugins aren't fully compatible with the incremental rebuilds, but I'd like to fix that in the future. - Remove WEBrick hack to enable previewing with default URL paths (/ instead of /index.html). - Filter out compliants from Rouge README.md: - Now that Alerts (_alerts) are part of a collection, the file names are no longer parsed for dates, so instructions on adding the date to the YAML metadata have been added. _alerts/*: - Now that alerts are part of a collection, the file names are no longer parsed to provide dates, so a `date:` field has been added to the YAML metadata. _config.yml: - Some variables renamed per upgrade instructions. - Switched from old default syntax highlighter Pygments to new default Rouge. I tried to use Rouge options to keep new output as similar to old output as possible to making diffing easy, but Rouge adds extra CSS class info. - Move `_alerts` and `_releases` into Jekyll 3.x "collections", which provide the organizational features we were using plugins to manange. I haven't removed the old plugins because we still use some of their features (alerts.rb provides active issue and banner features; releases.rb provides info to Download page) - _layouts/* can no longer provide default global metadata; that is now provided in the new `defaults:` section in _config.yml. _layouts/*: - Default metadata can no longer be provided in the layout files for collections, so I've removed it and left a message to see _config.yml. _plugins/*: - Remove filter_for.rb. It's completely broken on Jekyll 3.x because of changes to Liquid which prevent adding new arguments to the inherited Liquid::For class. Existing uses of filter_for have been migrated to built-in for loops prefaced by sorts. - Remove remove-html-extension.rb: at it said in the comments, this was a temporary hack to get us to Jekyll 3.0. _releases/*: - Rename all the files: prefix a v to the file name so the output html (e.g. v10.0.0.html) is the same as the source filename (e.g. v10.0.0.md). This is necessary to migrate them to a Jekyll collection. - Remove %v from titles: we have to explicitly set the title, like we used to. Again required for migration to collections. _templates/events.html & en/rss/events.rss: - Sort events by date and then loop with regular for loop rather than filter_for en/alerts.html & en/rss/alerts.rss: - Sort alerts by date and then loop with regular for loop rather than filter_for en/bitcoin-core/index.md & en/version-history.html & en/rss/releases.rss: - Sort alerts by date and then loop with regular for loop rather than filter_for

<h2 id="what-happened">What happened</h2>
|
|
|
|
<p>The version of OpenSSL used by Bitcoin Core software version 0.9.0 and earlier
|
|
contains a bug that can reveal memory to a remote attacker. See
|
|
<a href="http://heartbleed.com/">http://heartbleed.com/</a>
|
|
for details.
|
|
</p>
|
|
|
|
<h2 id="what-you-should-do">What you should do</h2>
|
|
|
|
<p>Immediately upgrade to <a href="/en/download">Bitcoin Core version 0.9.1</a> which is linked against
|
|
OpenSSL version 1.0.1g.
|
|
|
|
If you use the official binaries, you can verify the version of OpenSSL being
|
|
used from the Bitcoin Core GUI's Debug window (accessed from the Help menu).
|
|
If you compiled Bitcoin Core yourself or use the Ubuntu PPA, update your
|
|
system's OpenSSL.
|
|
|
|
Linux users should also upgrade their system's version of OpenSSL.
|
|
</p>
|
|
|
|
<h3 id="android">Android</h3>
|
|
|
|
<p>Android version 4.1.1 is vulnerable to Heartbleed. Try if you can upgrade to at
|
|
least Android 4.1.2. If you are using Bitcoin Wallet on an Android phone, you
|
|
should upgrade the app to at least version 3.45.</p>
|
|
|
|
<h2 id="how-serious-is-the-risk">How serious is the risk</h2>
|
|
|
|
<p>If you are using the Windows version of the Bitcoin Core GUI without a wallet
|
|
passphrase, it is possible that your wallet could be compromised by clicking
|
|
on a bitcoin: payment request link.
|
|
|
|
If you are using bitcoind (on Linux, OSX, or Windows),
|
|
have enabled the -rpcssl option, and allow RPC connections
|
|
from the Internet, an attacker from a whitelisted (-allowip) IP address can
|
|
very likely discover the rpcpassword and the last rpc request. It is possible
|
|
(but unlikely) private keys could be sent to the attacker.
