=dev-ruby/rails-2.3.15 and its dependencies are now in the tree and can be marked stable.

[Comment 2 Alex Legler (RETIRED) 2013-01-09 08:10:10 UTC]

Arches, please test and mark stable:

=dev-ruby/activesupport-2.3.15
=dev-ruby/activeresource-2.3.15
=dev-ruby/actionpack-2.3.15
=dev-ruby/actionmailer-2.3.15
=dev-ruby/activerecord-2.3.15
=dev-ruby/rails-2.3.15

Target KEYWORDS: "amd64 ppc ppc64 x86"

[Comment 3 Hans de Graaff 2013-01-09 09:19:04 UTC]

Rails 3.0.19, 3.1.10, and 3.2.11 are now also in the gentoo tree.

[Comment 4 Wim van Ravesteijn 2013-01-09 13:57:38 UTC]

Please undelete files/activesupport-2.3.5-mocha-0.9.5.patch from dev-ruby/activesupport, it is still referenced from the 2.3.15 ebuild.

Without this file, dev-ruby/activesupport-2.3.15 does not build (on amd64)

[Comment 5 Agostino Sarubbo 2013-01-09 15:01:20 UTC]

amd64 stable

[Comment 6 Agostino Sarubbo 2013-01-09 15:03:11 UTC]

x86 stable

[Comment 7 Agostino Sarubbo 2013-01-09 15:06:16 UTC]

[Comment 8 Agostino Sarubbo 2013-01-09 15:14:17 UTC]

[Comment 9 Tim Sammut (RETIRED) 2013-01-09 20:08:42 UTC]

Thanks, everyone. Added to existing GLSA request.

[Comment 10 Hans de Graaff 2013-01-15 07:33:56 UTC]

Contrary to earlier report "Unsafe Query Generation Risk in Ruby on Rails" also affects the 2.3.x series. The upstream advisory has been updated accordingly and issued a patch which has been applied in:

=dev-ruby/activerecord-2.3.15-r1

CVE-2013-0156 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-0156):
  active_support/core_ext/hash/conversions.rb in Ruby on Rails before 2.3.15,
  3.0.x before 3.0.19, 3.1.x before 3.1.10, and 3.2.x before 3.2.11 does not
  properly restrict casts of string values, which allows remote attackers to
  conduct object-injection attacks and execute arbitrary code, or cause a
  denial of service (memory and CPU consumption) involving nested XML entity
  references, by leveraging Action Pack support for (1) YAML type conversion
  or (2) Symbol type conversion.

CVE-2013-0155 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-0155):
  Ruby on Rails 3.0.x before 3.0.19, 3.1.x before 3.1.10, and 3.2.x before
  3.2.11 does not properly consider differences in parameter handling between
  the Active Record component and the JSON implementation, which allows remote
  attackers to bypass intended database-query restrictions and perform NULL
  checks or trigger missing WHERE clauses via a crafted request, as
  demonstrated by certain "[nil]" values, a related issue to CVE-2012-2660 and
  CVE-2012-2694.
