issues found after scanning drupal installation with retina

hi there ,

i used retina , for scanning a drupal installation and following issues were reported , i found some suggestions to each issue and want to know if :

Issue : Web Application /html/?options[style_dir] Vulnerabilities :: The presence of the URI '/html/?options[style_dir]=../../../../../../../etc/junk'
Solution : filter options[style_dir] to accept valid directory paths only
Question : Does drupal do that ?

Issue:Web Application index.php?s=-badrow Globally Detected
Solution : escaping input data
Question : does drupal do that ?

any ideas ?
thanks
