233=head1 SECURITY CONSIDERATIONS
234
235CV uses Pixbuf to load images. Pixbuf is not considered safe for this
236purpose, though (from the gtk-2.2 release notes):
237
238"While efforts have been made to make gdk-pixbuf robust against invalid
239images, using gdk-pixbuf to load untrusted data is not recommended, due to
240the likelyhood that there are additional problems where an invalid image
241could cause gdk-pixbuf to crash or worse."
56 242
57=head1 BUGS/TODO 243=head1 BUGS/TODO
244
245 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
246 incompatible with utf-8 fails.
