Description Pedro Sampaio 2017-12-14 20:45:12 UTC 
** DISPUTED ** tools/url_handler.pl in TIN 2.4.1 does not validate strings
   before launching the program specified by the BROWSER environment
   variable, which might allow remote attackers to conduct argument-injection
   attacks via a crafted URL. NOTE: a third party has reported that this is
   intentional behavior, because the documentation states "url_handler.pl was
   designed to work together with tin which only issues shell escaped
   absolute URLs."
