JRuby 1.6.6 Released

Monday, January 30 2012

The JRuby community is pleased to announce the release of JRuby 1.6.6.

Homepage: http://www.jruby.org/
Download: http://www.jruby.org/download

The primary goal of the 1.6.x series is to round out our 1.9 support by fixing any reported incompatibilities. Of course, as with any JRuby release, we will continue fixing any found incompatibilities and also improve performance. All users of 1.6.5.1 (and lower) are encouraged to upgrade to 1.6.6.

Because master keeps getting further and further away from our 1.6 branch we have decided to make this our last 1.6 release. We largely fulfilled our goal of having reasonable 1.9 support. Follow up fixes for 1.9 support will only be fixed on master from this point forward. JRuby 1.7.0 will be the next release of JRuby.

Notable Changes:

Updated stdlib to match Ruby 1.8.7p357 and 1.9.2p312
Updated RubyGems to 1.8.15
Multiple 1.9-mode yield/splat bugs fixed (pp, rspec 2.8 working again)
Multiple 1.9-mode encoding bugs fixed
Critical fixes in Random and Fiber
Map Scala operator methods to symbolic names ($plus, etc)

JRuby 1.6.5.1 Released

Tuesday, December 27 2011

The JRuby community is pleased to announce the release of JRuby 1.6.5.1.

Homepage: http://www.jruby.org/
Download: http://www.jruby.org/download

JRuby 1.6.5.1 is a special release with a single patch applied to our JRuby 1.6.5 source to correct CERT vulnerability CERT-2011-003. All users are recommended to upgrade to JRuby 1.6.5.1 to get this security fix.

A fuller JRuby 1.6.6 with bug fixes from the last two months will be released mid-January…

Background for the CERT advisory:

(for the impatient: predictable hashing algorithm and open access to a hash from a server can possibly allow Denial of Service (DOS) attacks)

Hashing 101

Hash tables apply a math function (hashing function) to the key of a key-value pair. The result of the hashing function is a location to a hash bucket which stores the key/value pair internally:

a[:heh] = 1
hashing_function(:heh) -> store :heh/1 in hash bucket #3
a[:foo] = 2
hashing_function(:foo) -> store :foo/2 in hash bucket #13
a[:bar] = 3
hashing_function(:bar) -> store :bar/3 in hash bucket #1

Hashes have many buckets and in theory all key/value pairs added to a hash will get spread out evenly across the hashes buckets. In practice, some number of keys will end up hashing into the same hash bucket (known as a hashing collision). As you get more key/value pairs stored to the same hash bucket the time to access those particular key/value pairs will slow down. This is because you need to walk some portion of the entries in the bucket to find the specific one you are looking for (hash structures will often make entries in an individual bucket a simple list structure).

a[:gar] = 4
hashing_function(:gar) -> store gar/4 in hash bucket #3 (same bucket as :heh)

In this example, accessing a[:gar] and a[:heh] may take longer than the other keys because they are sharing a hash bucket.

The Attack

The general application of the attack is for “the bad guys” to figure out a large set of values which will hash to the same hash bucket. Once they create this list they will send all those values to a server. The server will store them in a hash (think parameter list in Rack, for example). The act of storing or accessing any of those values takes longer and longer as the number of entries in a single hash bucket grows. The result will be a Denial Of Service (DOS) attack if enough values get stored.

hashing_function(:hostname) -> hash bucket #3
hashing_function(:aZ1) -> hash bucket #3
hashing_function(:cvg) -> hash bucket #3
hashing_function(:azr) -> hash bucket #3
... # many elided
hashing_function(:1fr) -> hash bucket #3
hashing_function(:yu3) -> hash bucket #3
hashing_function(:hyX) -> hash bucket #3

host = params[:hostname] # Uh oh! need to find this amongst many bucket buddies

The Fix

Adding a little bit of randomization to the hashing algorithm ends up making it much, much more difficult to figure out how to generate this type of attack. JRuby 1.6.5.1 (and all later JRuby releases) all have this additional randomization built into the hashing algorithm. The result should be decent hash bucket distribution that is difficult for attackers to predict. More information

This vulnerability is not exclusively an issue of JRuby. Other Ruby implementations also have a similar issue (also patched today). In fact, Java and PHP also appear to be susceptible to this style of attack. For more information, please see the CERT announcement.

Also, consider that language implementations are really only susceptible to this attack via frameworks which allow an external hacker to store arbitrary and/or unbounded key/values into a hash. Ruby Rack had this vulnerability, but they have fixed things so that the amount of parameters stored is bounded by a size to remove the possibility of a DOS attack. Rack users should upgrade to the latest version.

This release integrates experimental support for C extensions based on Ruby’s C API. And as with all major releases, we have improved stability and performance across the board in response to real-world user input.

Over the next month or two we plan on putting out quicker point releases in anticipation that 1.6.0 will get a new wave of feedback. Give JRuby 1.6.0 a try and let us know how things go.

Major Features:

Ruby 1.9.2 language and API compatibility
- Not implemented Encoding::Converter, ripper
Improved Ruby call performance
Built-in profiler (–profile, –profile.graph)
RSpec no longer bundled
C Extension support (experimental)

- Encoding issues (especially involving Regexp)
- Fiddle implementation

JRuby 1.5.0 Released

Wednesday, May 12 2010

The JRuby community is pleased to announce the release of JRuby 1.5.0.

Homepage: http://www.jruby.org/
Download: http://www.jruby.org/download

This development cycle has been our longest cycle yet (nearly 5 months), but it also has the most fixes. It also includes many new notable features (see below). Most of our bug fixes have been more of what we consider fine-tuning, since we keep getting into smaller corner-cases of compatibility for individual Ruby methods. In that sense, we expect if you had a good experience with JRuby 1.4.0 then 1.5.0 will be a no-brainer upgrade. If you haven’t tried JRuby in a while with your application, then please give us another try. Odds are whatever issue you were having before no longer exists!

1.5.0 Highlights:

New native access framework designed for performance and better FFI support
Native launcher for *NIX platforms
Ant support and Rake-Ant integration
Better and better support for Windows
Multiple performance improvements for Ruby-to-Java calling, improving correctness, memory, and speed.
Embedding API improvements based on user input (JSR-223, BSF, RedBridge, etc)
Software updates: Ruby 1.8.7 standard library update, RubyGems 1.3.6, RSpec 1.3.0
ruby-debug installed by default
Many fixes for Rails 3
Various improvements to startup time
Improved performance for Object#object_id/__id__
Reduced memory use for Java class metadata and faster loading of Java classes
jar-in-jar support in the classloader
The “open4” library now works properly
jruby.jit.codeCache=dir to save jitted scripts/methods to disk in a sha1-hashed .class file
New logic for interface implementation that produces “real” classes
jruby.ji.objectProxyCache to turn off OPC for extra performance
JRuby::Synchronized module for making a class and its subclasses 100% synchronized on all calls
Miscellaneous perf improvements to core classes and minor improvements in the JIT
No more ObjectSpace during IRB
Cleaned up maven artifacts
Windows Installer fixes for x64 and Windows 7 security
Over 1250 commits since JRuby 1.4

We always appreciate community contributions. This cycle we’ve had more help than ever: David Calavera, Stephen Bannasch, Daniel Luz, Ian Dees, Koichiro Ohba, Hongli Lai, Hiroshi Nakamura, Colin Jones, Takeru Sasaki, Roger Pack, Matjaz Gregoric, Joseph LaFata, Frederic Jean, Alex Coles, Lars Westergren

Most of our bug fixes have been more of what we consider fine-tuning, since we keep getting into smaller corner-cases of compatibility for individual Ruby methods. In that sense, we expect if you had a good experience with JRuby 1.4.0 then 1.5.0.RC3 will be a no-brainer upgrade. If you haven’t tried JRuby in a while with your application, then please give us another try. Odds are whatever issue you were having before no longer exists! And we would really like help making sure JRuby 1.5.0 final is a solid release…so please try and report back with any problems.

1.5.0 Highlights:

New native access framework designed for performance and better FFI support
Native launcher for *NIX platforms
Ant support and Rake-Ant integration
Better and better support for Windows
Multiple performance improvements for Ruby-to-Java calling, improving correctness, memory, and speed.

JRuby 1.4.1 Released - Fixes XSS Vulnerability in JRuby 1.4.0 - Recommended Upgrade

Monday, April 26 2010

Today we’re releasing JRuby 1.4.1 as a recommended upgrade for all previous versions of JRuby. Previous versions contained a bug in JRuby’s regular expression engine that could allow an attacker to perform, for example, an XSS attack on a web application running under JRuby.

Download the 1.4.1 release.

This vulnerability fix is the only change from the previous JRuby release (1.4.0). Also note that the JRuby 1.5.0 release contains this fix as well.

Common Vulnerabilities and Exposures

The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2010-1330 to this issue. This is a candidate for inclusion in the CVE list, which standardizes names for security problems.

Impact

Any Ruby application code that uses regular expressions for string matching and substitution running under JRuby and using $KCODE = 'u' is vulnerable.

If a string contains invalid UTF-8 byte sequences in the (inclusive) range \xC0 to \xFD, the immediately following character will not be matched by a regular expression. Consider the following code:

str = "\xF6<script>"

$KCODE = ''
puts "KCODE: " + $KCODE
puts str.gsub(/</, "&lt;")

$KCODE = 'u'
puts "KCODE: " + $KCODE
puts str.gsub(/</, "&lt;")

Ruby 1.8.7 ignores the invalid bytes and continues, while Ruby 1.9.2 raises an ArgumentError due to the invalid bytes. But for JRuby, the effect is to fail to match the character following the invalid byte. For the example above example run with JRuby 1.4.0 prints the following. Note that the fourth line should be the same as the second.

KCODE: NONE
?&lt;script>
KCODE: UTF8
?<script>

The effect of this bug is magnified considering that the Rails html_escape or h helper essentially does what the above example does, meaning that any Rails view using the standard ERb escape helper method is vulnerable.

Releases

The JRuby 1.4.1 and 1.5.0 releases (including release candidates) all have the vulnerability fixed.

The fix was applied to the jcodings library which JRuby uses. As such, a source patch against the JRuby source is not available. Replacing the build_lib/jcodings.jar file in your JRuby source build with the jcodings version 1.0.3 jar file is sufficient to resolve the issue.

If you are unable to upgrade to JRuby 1.4.1, please contact the JRuby team at security@jruby.org for assistance.

Workarounds

Turn off $KCODE = 'u' in your application if you can. Otherwise, the only approach is to patch application or framework code to be aware of the invalid byte sequences.

Thanks

Many thanks to Jörn Hartmann (joern dot hartmann at gmail dot com) for finding and reporting the issue.

JRuby 1.5.0.RC1 Released

Thursday, April 15 2010

The JRuby community is pleased to announce the release of JRuby 1.5.0.RC1

Homepage: http://www.jruby.org/
Download: http://www.jruby.org/download

This development cycle has been our longest cycle yet (nearly 5 months), but it also has the most fixes. It also includes many new notable features (see below). Most of our bug fixes have been more of what we consider fine-tuning, since we keep getting into smaller corner-cases of compatibility for individual Ruby methods. In that sense, we expect if you had a good experience with JRuby 1.4.0 then 1.5.0.RC1 will be a no-brainer upgrade. If you haven’t tried JRuby in a while with your application, then please give us another try. Odds are whatever issue you were having before no longer exists! And we would really like help making sure JRuby 1.5.0 final is a solid release…so please try and report back with any problems.

1.5.0.RC1 Highlights:

New native access framework designed for performance and better FFI support
Native launcher for *NIX platforms
Ant support and Rake-Ant integration
Better and better support for Windows
Multiple performance improvements for Ruby-to-Java calling, improving correctness, memory, and speed.

Various improvements to startup time
Improved performance for Object#object_id/__id__
Reduced memory use for Java class metadata and faster loading of Java classes

JRuby BugMash!

Tuesday, January 05 2010

Come join us this weekend, January 9-12, for the first ever JRuby BugMash!

The JRuby project has been growing impressively quickly, with frequent releases and a constantly expanding community. There’s a hefty list of impressive users and companies, and the team has been touring the world, trying their best to make it out to everyone who wants to hear and learn about the project.

As with any growing code base though, there’s a need to keep things tidy; frequent releases and speedy development also mean bugs, and things that need fixing–and that’s where we turn to you!

The first ever official JRuby BugMash will take place this Saturday, January 9th through Tuesday, January 12th. The core team will spend the days prior to the BugMash highlighting the specific bugs that are most important–you’ll want to keep an eye out for the Intro section. Then, Saturday morning, it’s off to the races! As a small token of our appreciation, in addition to the wonderful satisfaction of having made a difference to the project, we’ll be sending each of the first 100 participants a limited edition JRubyConf Poster. There are some more ‘tokens of appreciation’ up our sleeves for the top contributors, but we’ll keep those secret for now.

The JRuby Core Team will be around on IRC channel #jruby throughout the BugMash to help folks get started and to answer questions. Be sure to stop in and say hello!

Vulnerability in jruby-openssl < 0.6 - Recommended Upgrade

Monday, December 07 2009

A security problem involving peer certificate verification was found where failed verification silently did nothing, making affected applications vulnerable to attackers. Attackers could lead a client application to believe that a secure connection to a rogue SSL server is legitimate. Attackers could also penetrate client-validated SSL server applications with a dummy certificate.

Common Vulnerabilities and Exposures

The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2009-4123 to this issue. This is a candidate for inclusion in the CVE list, which standardizes names for security problems.

Impact

Your application would be vulnerable if you’re using the OpenSSL::SSL::VERIFY_PEER mode on an OpenSSL-enabled socket (client or server) and any version of jruby-openssl prior to 0.6. An example using client-side validated SSL with the ‘net/https’ library is shown below.

  require 'net/https'
  uri = URI.parse('https://www.amazon.com/')
  http = Net::HTTP.new(uri.host, uri.port)
  http.use_ssl = true
  http.verify_mode = OpenSSL::SSL::VERIFY_PEER

  # This code should raise OpenSSL::SSL::SSLError
  # because it's not the correct trust anchor for
  # www.amazon.com.
  http.ca_file = 'test/fixture/verisign_c3.pem'
  response = http.start do |s|
    s.get(uri.request_uri)
  end

  # This code must fail as well because of an incorrect
  # trust anchor setting (no certs is the directory).
  http.ca_path = '/tmp'
  response = http.start do |s|
    s.get(uri.request_uri)
  end

  # verisign.pem is the correct trust anchor for www.amazon.com.
  # Only this request should be successful.
  http.ca_file = 'test/fixture/verisign.pem'
  response = http.start do |s|
    s.get(uri.request_uri)
  end

Release and Patch

The 0.6 release has the fix for the certificate validation vulnerability. Install the upgrade in the usual fashion by running jruby -S gem install jruby-openssl and ensuring that you get version 0.6 or greater.
A patch is available which should apply cleanly to the jruby-openssl 0.5.2 source. Ensure the code builds cleanly and passes tests by running jruby -S rake clean default.
Please contact security@jruby.org if you are unable to upgrade or use the 0.5.2 patch and require a backport. Let us know what version of jruby-openssl you’re using and help us understand how you’re using the library so we can determine whether you’re affected by the vulnerability.

Workarounds

No known workarounds exist, other than rewriting application code to use a different library to establish validated SSL connections.

Thanks

Thanks to NaHi (NAKAMURA Hiroshi - nahi at ruby-lang.org) for finding the problem and providing the fix.

JRuby 1.4.0 Released

Monday, November 02 2009

The JRuby community is pleased to announce the release of JRuby 1.4.0

Homepage: http://www.jruby.org/
Download: http://www.jruby.org/download

After three very helpful release candidates we have a final 1.4.0 release. This release ends a long release cycle in which we resolved a huge number of issues. The headline feature is a move to Ruby 1.8.7 support, in line with Rails’ own plans to make 1.8.7 the required minimum version of Ruby.

We have also gotten more serious about out 1.9 support (–1.9). The bigger applications mostly just work at this point, but we still have a ways to go on 1.9 support. Please try your 1.9 code in JRuby and help us firm things up.

1.4.0 Highlights:

JRuby is now compatible with 1.8.7 patchlevel 174
Windows Native Launcher - Solves many reported bugs with our old .bat scripts
New YAML parser Yecht (bug-for-bug compatible with Syck!)
Improved Java Integration Support
- faster
- new java_method, java_send, and java_alias methods
Windows installer
New embedding framework
- Java 6 scripting out of the box
- New org.jruby.embed package to supersede JavaEmbedUtils
Many 1.9 mode (–1.9) fixes
- updated stdlib to 1.9.2preview2
- Rubygems now working
- Rails 2.3.3 simple apps working (2.3.4 has 1.9 bug)
rubygems 1.3.5
Much better error reporting
- shorter backtraces with less Java
- Ruby-compatiable syntax error reporting
307 bugs fixed since 1.3.1

We want to thank all the users who have been helping us to get a better release out. Special thanks to Hiro Asari, David Calavera, and Roger Pack for their recent activity in the project. We also want to welcome Yoko Harada as a committer to the project. Her work and support of our embedding efforts has been great.

JRuby 1.4.0RC3 Released

Wednesday, October 28 2009

The JRuby community is pleased to announce the release of JRuby 1.4.0RC3

Homepage: http://www.jruby.org/
Download: http://www.jruby.org/download

Third time is a charm! Actually, this third release candidate is largely for the benefit of our Windows users. We have gotten reports of issues with our new installer and our new native launcher and we have been trying to make sure JRuby on Windows is a pleasant experience. We also fixed a Socket regression which had caused celerity to break.

The JRuby 1.4.0 release ends a long release cycle in which we resolved a huge number of issues. The headline feature is a move to Ruby 1.8.7 support, in line with Rails’ own plans to make 1.8.7 the required minimum version of Ruby.

Please try your apps against 1.4.0RC3 ASAP and report problems

1.4.0RC1-RC3 Highlights:

JRuby is now compatible with 1.8.7 patchlevel 174
Windows Native Launcher - Solves many reported bugs with our old .bat scripts
New YAML parser Yecht (bug-for-bug compatible with Syck!)
Improved Java Integration Support
- faster
- new java_method, java_send, and java_alias methods
Windows installer
New embedding framework
- Java 6 scripting out of the box
- New org.jruby.embed package to replace JavaEmbedUtils
Many 1.9 mode (–1.9) fixes
- updated stdlib to 1.9.2preview2
- Rubygems now working
- Rails 2.3.3 simple apps working (2.3.4 has 1.9 bug)
rubygems 1.3.5
Much better error reporting
- shorter backtraces with less Java
- Ruby-compatiable syntax error reporting
241 bugs fixed since 1.3.1

Issues fixed between 1.4.0RC2 and 1.4.0RC3:

Key             Summary
JRUBY-4150      rake --trace causes dialog box (Missing argument) on Windows

JRuby 1.4.0RC2 Released

Wednesday, October 21 2009

The JRuby community is pleased to announce the release of JRuby 1.4.0RC2.

Homepage: http://www.jruby.org/
Download: http://www.jruby.org/download

Due to the overwhelming feedback we got from RC1, we have fixed a number of reported issues (shown below) for RC2. We expect that this will be our last RC before 1.4.0 final.

Please try your apps against 1.4.0RC2 ASAP and report problems.

1.4.0RC2 Highlights:

Windows Native Launcher
- Solves many reported bugs with our old .bat scripts

1.4.0RC1 Highlights:

JRuby is now compatible with 1.8.7 patchlevel 174
New YAML parser Yecht (bug-for-bug compatible with Syck!)
Improved Java Integration Support
- faster
- new java_method and java_send methods
Windows installer
New embedding framework
- Java 6 scripting out of the box
- New org.jruby.embed package to replace JavaEmbedUtils
Many 1.9 mode (–1.9) fixes
- updated stdlib to 1.9.2preview2
- Rubygems now working
- Rails 2.3.3 simple apps working (2.3.4 has 1.9 bug)
rubygems 1.3.5
Much better error reporting
- shorter backtraces with less Java
- Ruby-compatiable syntax error reporting
232 bugs fixed since 1.3.1

We want to give a couple of special acknowledgements for some contributors who went the extra mile this release cycle.

David Calavera has done a great job wrestling with Rubyspec failures and coming up with patches.

Yoko Harada has totally revamped our embedding APIs and created a new API called Red Bridge. This should address all of the reported embedding issues.
