Synopsis
=======
Multiple vulnerabilities have been discovered in Rails, the worst of
which leading to the execution of arbitrary SQL statements.
Background
=========
Ruby on Rails is a web-application and persistence framework.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-ruby/rails < 2.2.2 >= 2.3.5
*>= 2.2.3-r1
==========
The following vulnerabilities were discovered:
* sameer reported that lib/action_controller/cgi_process.rb removes
the :cookie_only attribute from the default session options
(CVE-2007-6077), due to an incomplete fix for CVE-2007-5380 (GLSA
200711-17).
* Tobias Schlottke reported that the :limit and :offset parameters of
ActiveRecord::Base.find() are not properly sanitized before being
processed (CVE-2008-4094).
* Steve from Coderrr reported that the CRSF protection in
protect_from_forgery() does not parse the text/plain MIME format
(CVE-2008-7248).
* Nate reported a documentation error that leads to the assumption
that a block returning nil passed to
authenticate_or_request_with_http_digest() would deny access to the
requested resource (CVE-2009-2422).
* Brian Mastenbrook reported an input sanitation flaw, related to
multibyte characters (CVE-2009-3009).
* Gabe da Silveira reported an input sanitation flaw in the
strip_tags() function (CVE-2009-4214).
* Coda Hale reported an information disclosure vulnerability related
to HMAC digests (CVE-2009-3086).
Impact
=====
A remote attacker could send specially crafted requests to a vulnerable
application, possibly leading to the execution of arbitrary SQL
statements or a circumvention of access control. A remote attacker
could also conduct session fixation attacks to hijack a user's session
or bypass the CSRF protection mechanism, or furthermore conduct
Cross-Site Scripting attacks or forge a digest via multiple attempts.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All Ruby on Rails 2.3.x users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-ruby/rails-2.3.5"
All Ruby on Rails 2.2.x users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose "=dev-ruby/rails-2.2.3-r1"
NOTE: All applications using Ruby on Rails should also be configured to
use the latest version available by running "rake rails:update" inside
the application directory.
