196=head1 SECURITY CONSIDERATIONS
197
198CV uses Pixbuf to load images. Pixbuf is not considered safe for this
199purpose, though (from the gtk-2.2 release notes):
200
201"While efforts have been made to make gdk-pixbuf robust against invalid
202images, using gdk-pixbuf to load untrusted data is not recommended, due to
203the likelyhood that there are additional problems where an invalid image
204could cause gdk-pixbuf to crash or worse."
122 205
123=head1 BUGS/TODO 206=head1 BUGS/TODO
207
208 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
209 incompatible with utf-8 fails.
