Obviously this problem is not clear. A very similar problem ,like the
"HTTP Response Splitting" ,Whose vulnerability? webapp or Server-side
language?

so we come back this vul need two Conditions

1.www.google.com app don't filter the CRLF

2.IE support mhtml protocol handler to render the mhtml file format,
and this is the why mhtml: is designed


so the football game is going ....

I woudn't like to discourage ppl submitting vulns to vendors but this is the
response you'll most likely to get from those kind of vendors no matter what
you found in their system. I had more than a dozen similar experience like
yours. Now it's public + fixed and you gotta get nothing beside these
replies (:

I think you'd be surprised. Our reward panel consists solely of people
you would recognize from this list, BUGTRAQ, or vendor advisories; and
we are very consistent, timely, and pretty generous in rewarding a
large proportion of all incoming reports. Ask around :-)

In this particular case, though, the underlying problem is clearly a
browser-side flaw that is nearly impossible to fully address on web
application side - and one that first surfaced in 2004, then wasn't
fully fixed in 2007:

Even in cases like this, we sometimes reward the reporter when we are
given advance notice, and there are clear ways we can protect our
users. But in this instance, the report is already public, we are
already aware it, and we are trying to deploy basic workarounds in a
number of exposed spots; and as noted, realistically, there is a
limited recourse any web app provider will have.
