Description Doran Moppert 2017-09-28 04:28:43 UTC
Several fonts on OS X display some Tibetan and Arabic characters as whitespace. When used in the addressbar as part of an IDN this can be used for domain name spoofing attacks. 

*Note: This attack only affects OS X operating systems. Other operating systems are unaffected.*
