192=head1 SECURITY CONSIDERATIONS
193
194CV uses Pixbuf to load images. Pixbuf is not considered safe for this
195purpose, though (from the gtk-2.2 release notes):
196
197"While efforts have been made to make gdk-pixbuf robust against invalid
198images, using gdk-pixbuf to load untrusted data is not recommended, due to
199the likelyhood that there are additional problems where an invalid image
200could cause gdk-pixbuf to crash or worse."
123 201
124=head1 BUGS/TODO 202=head1 BUGS/TODO
203
204 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
205 incompatible with utf-8 fails.
