Brian Mastenbrook discovered that rails, the MVC ruby based framework geared for web application development, is prone to cross-site scripting attacks via malformed strings in the form helper.

The remote host is affected by the vulnerability described in GLSA-200912-02 (Ruby on Rails: Multiple vulnerabilities)

    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.

A vulnerability is found on Ruby on Rails in the escaping code for the form helpers, which also affects the rpms shipped in Fedora Project.
Attackers who can inject deliberately malformed unicode strings into the form helpers can defeat the escaping checks and inject arbitrary HTML. This issue has been tagged as CVE-2009-3009. These new rpms will fix this issue.
