Jeremy, i can't see how it will make things any worse to punch these holes
you still fork flash in its own process like you do now
only you sandbox it how is it any worse ?

this is just an observation that if i would write malware (which of course,
i would never)
i would just use flash plugins exploits to be cross browser compatible
and this renders the sandbox nearly useless for future attacks

what decent malware writer would bother with webkit explits ? none!

besides, if you look at the help forum of chrome, you will see some people
are starting to catch malware like this
which is btw, how i got this evil site's URL i would never click on my
own such a foul looking site

as for the auto updating issue, i suggested a solution in one of my prev
posts
and i am sure you can have a word with adobe for this

in a sense chrome makes it easier to infect itself(!) as you run plugins in
the medium integrity level (Vista and above)
and you normally install chrome in the local user account, so no UAC prompt
will help the user
if some delicate file or DLL is written to chrome folder, and then it will
do something never intended

also, one more note, flash is special enough that if you would hard code
the solution to it, you would anyays
solve most infections problems in the world, and maybe even cancer... who
knows ?

and regarding what CPU said (and ignoring the auto-update) it seems that
flash does work flawlessly
using your '--safe-plugins' switch, and doing this on that site does stop
the attack
(tbh, maybe the attack was stopped because the sun's java died in the
sandbox, but Ian said it was a flash based
attack)

2009-08-06 Thread yoav zilberberg
Alex, your reply irritates me so much that i am willing to take my chancesand
if anyone (from @chromium) finds my answer insulting e-mail me and i will
remove myself
forever from your lists, promise!

what kind of an answer is that ?
do you know how this attack was carried ?
did you even read this thread before suggesting your comments ?

even the start of your thread trust the force is so arrogant, and while i
don't know who carlos is
i would think that even carlos would know that if you intercepted file
access you would have
easily stopped this attack.

jeremy was at least constructive, in suggesting i would patch it myself, but
like i said, i don't know NPAPI
nor do i know flash for that matter

but i do know windows, alex, and whatever flash does internally he cannot
access the disk directly, right ? (of course not)
so just that simple test would have been enough

and again, if anyone(!) from chrome(!) finds my response offensive, reply
here and i promise never to post here again
with zero hard feelings

2009-08-06 Thread yoav zilberberg
Ian, well, i like your reply, so just tell me please for my own knowledge
one thing
is there ever a reason to allow flash (we are talking only flash here) to
fork WinMail.exe for example ?

i am a very light weight surfer, and i mostly read tech stuff, so my
experience with flash is mostly youtube

is this really something which any flash application does ?

does flash really expect to have access to 'program files' ?

if flash is expected to have access to it all, then you wouldn't have tried
to sandbox it in the first place, right ?
and btw, i read really a lot of the source code of chrome, and i still do, i
even used your sandbox API
to various tricks, and i even submitted patches and expect to do more in the
future

2009-08-06 Thread yoav zilberberg
No adam, i did not sumbit patches to the sandbox :) i just used its API's to
forward calls from kernel32.dll to my own DLL's so i could inject code to
VC.exe and force it to run in the idle priority class
but i still don't get it
if Flash expects to be able to SendMessage, then you cannot sandbox it
anyways as there is no limit to what can be done
and of course, i also look forward to HTML5

All i am saying is that one of the biggest selling points of chrome is that
it is secure (no drive by malware anymore)
and i was hoping from such a good produce as chrome to protect me

there is simple statistics to be had here
do most flash apps expect to the able to SendMessage ? if so, i admit, this
is a hopeless case
but if not, then you should have added an option in chrome to say
'sandbox flash by default' and then you could whitelist some sites you trust

2009-08-06 Thread yoav zilberberg
Alex, let me get it, are you part of the chrome team ? i don't recall
accusing anyone from chromebut i do recall not liking your reply, so just
let me know if you are part of the devs of chrome please

i will be honest, if you are, then i think it is time for me to move to a
different browser, if you are not
then don't decide if i accuse the chrome team or not, let them tell me, and
like i said
i would remove myself in a second and with no hard feelings

[chromium-dev] Re: 2 Questions about Npapi (and flash in particular)

2009-08-02 Thread yoav zilberberg
i have none. if i could do it on my machine i would debug it and
(fopefully) find the root cause
my intention in posting it here is that maybe the person who wrote NPAPI
will say
oh, this makes sense or maybe this thread will die ..

anyways, the address space issue seems to make sense in a way, but then
again, i never wrote anything with
flash or anything like it, so i don't know how they handle the Address space
issues (they really have only one process
for the plugin)

Evan thanx, but the 2nd part of the --safe-plugins, i know it works on dev,
and it does seem to create the plugininside the sandbox, so is this a good
solution security wise to suggest to people ?

2009-07-29 Thread yoav zilberberg
I registered my copy of VS2008, so the update came with windows update, i
actually had no idea they did anythingtill my builds started to fail.

http://support.microsoft.com/kb/971092/

there were actually 3 updates, but i guess they are ashamed or something,
two of them link nowhere now :)
and you'd prob better wait till they fix it
