191=head1 SECURITY CONSIDERATIONS
192
193CV uses Pixbuf to load images. Pixbuf is not considered safe for this
194purpose, though (from the gtk-2.2 release notes):
195
196"While efforts have been made to make gdk-pixbuf robust against invalid
197images, using gdk-pixbuf to load untrusted data is not recommended, due to
198the likelyhood that there are additional problems where an invalid image
199could cause gdk-pixbuf to crash or worse."
56 200
57=head1 BUGS/TODO 201=head1 BUGS/TODO
202
203 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
204 incompatible with utf-8 fails.
