Synopsis

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

2. Impact Information

Background

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

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.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

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

Code Listing 3.1: Resolution
