Description Josh Bressers 2009-06-01 18:47:08 UTC
Mozilla add-on developer Pavel Cvrcek reported that certain invalid unicode
characters, when used as part of an IDN, are displayed as whitespace in the
location bar. This whitespace could be used to force part of the URL out of
view in the location bar. An attacker could use this vulnerability to spoof
the location bar and display a misleading URL for their malicious web page.
