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"
