CWE: CWE-78 \u2014 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.

Code:
comics_document_finalize (GObject *object)
{
	ComicsDocument *comics_document = COMICS_DOCUMENT (object);

	if (comics_document->decompress_tmp) {
		if (comics_remove_dir (comics_document->dir) == -1)
			g_warning (_("There was an error deleting “%s”."),
				   comics_document->dir);
		g_free (comics_document->dir);
	}

	if (comics_document->page_names) {
                g_ptr_array_foreach (comics_document->page_names, (GFunc) g_free, NULL);
                g_ptr_array_free (comics_document->page_names, TRUE);
	}

	g_free (comics_document->archive);
	g_free (comics_document->selected_command);
