Security issues on Arclite and Fusion theme - Fix?

Hi,
Arclite and Fusion theme, give to the blog owner the possibility to add html code into footer.
But this code isn't get sanitized so it can contains anything for e.x <iframe>

I replaced in:
/arclite.footer.php (~line 34) the
<?php print get_option('arclite_footer'); ?>
with
<?php print wp_kses_post(get_option('arclite_footer')); ?>

and in /fusion/footer.php (~line 63)the

<?php print get_option('fusion_footer'); ?>

with

<?php print wp_kses_post(get_option('fusion_footer')); ?>

but, I'm sure some sanitition is need at the theme options page.
Can, someone help?

Thanks in advance
Lena
