This kind of bugs are already fixed in recent Mozilla browsers,
as shown in your reference [4].

[4] "setRequestHeader can be exploited using newline characters", 
Bugzilla bug 297078
https://bugzilla.mozilla.org/show_bug.cgi?id=297078 and 
"XMLHttpRequest allows dangerous request headers to be set", 
Bugzilla bug 302263
https://bugzilla.mozilla.org/show_bug.cgi?id=302263

see comment #15 of bug 297078.

Oh. I missed this. So - very good. And thanks for bringing this to Bugtraq's and mine
