Synopsis
========

A format string error has been discovered in Ruby-GNOME2, possibly
leading to the execution of arbitrary code.

Background
==========

Ruby-GNOME2 is a set of bindings for using GTK+ within the Ruby
programming language.

Affected packages
=================

    -------------------------------------------------------------------
     Package             /   Vulnerable   /                 Unaffected
    -------------------------------------------------------------------
  1  dev-ruby/ruby-gtk2      < 0.16.0-r2                  >= 0.16.0-r2

Description
===========

Chris Rohlf discovered that the "Gtk::MessageDialog.new()" method in
the file gtk/src/rbgtkmessagedialog.c does not properly sanitize the
"message" parameter before passing it to the gtk_message_dialog_new()
function.

Impact
======

A remote attacker could send a specially crafted string to an
application using Ruby-GNOME2, possibly leading to the execution of
arbitrary code with the privileges of the user running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Ruby-GNOME2 users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-ruby/ruby-gtk2-0.16.0-r2"
