Description Josh Bressers 2005-02-07 21:07:30 UTC

The Shmoo Group has discovered a homograph attack in a number of web browsers:
http://www.shmoo.com/idn/

This issue allows an attacker supply a domain name that looks like a common
name, but is an International Domain Name.  This issue would allow various
attacks to steal information from an unsuspecting vitim.

Chris,

Per our conversation last week, do you have any ideas on how we plan to fix
this?  Upstream removed this functionality, but we don't want to do this.
