Description

Peter McLarnan discovered that the internationalization component of Ruby on Rails does not properly encode parameters in generated HTML code, resulting in a cross-site scripting vulnerability. This update corrects the underlying vulnerability in the i18n gem, as provided by the ruby-i18n package.

The oldstable distribution (squeeze) is not affected by this problem; the libi18n-ruby package does not contain the vulnerable code.
