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.
For the stable distribution (wheezy), this problem has been fixed in
version 0.6.0-3+deb7u1.
For the unstable distribution (sid), this problem has been fixed in
version 0.6.9-1.
We recommend that you upgrade your ruby-i18n packages.
