502648 - (CVE-2009-2478) Crash when scrolling in Flash with wmode=transparent [NPSWF32.dll@0x50abd]

Status: RESOLVED WORKSFORME

(External Software Affecting Firefox Graveyard :: Flash (Adobe), defect)

Description

[u348128]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; nl; rv:1.9.1) Gecko/20090624 Firefox/3.5 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; nl; rv:1.9.1) Gecko/20090624 Firefox/3.5 (.NET CLR 3.5.30729)

This was first reported in bug 501304, but it seems a different bug.

From top crash reports, the following page crashes:, with good reproducibility:

http://www.crazyprofile.com/water_effect/water_effect.asp

Wait before everything is loaded. Then scroll down. Bang! Consistent.

A minimized version can be found here:

http://web.inter.nl.net/users/L.B.Kruijswijk/FFflashcrash.html

Important is:
- The flash animation must be outside the visible screen when loading.
- Scroll down to get the crash.
- The wmode='transparent' parameter is important. When I remove it, it doesn't
crash anymore.





Reproducible: Always

Steps to Reproduce:
1. Go to site.
2. Wait until everything is loaded.
3. Scroll down.
Actual Results:  
Crash.

Expected Results:  
No crash.

Can someone confirm this bug?

Can someone check with 3.0.11? I don't have that version on my PC anymore.

I only volunteer to reproduce bugs, I won't analyze this further.

[Henrik Skupin [:whimboo][⌚️UTC+2] (away 10/03 - 10/13)]

Lucas, can you please attach your reduced testcase to this bug? Then we can take care of it. Thanks for your work.

Comment 3

[Henrik Skupin [:whimboo][⌚️UTC+2] (away 10/03 - 10/13)]

Michelle, could the Adobe team please have a look at this bug? It's highly reproducible and happens with the latest Flash version installed.

Regression range is: http://bonsai.mozilla.org/cvsquery.cgi?module=PhoenixTinderbox&date=explicit&mindate=2006-06-06+09%3A00&maxdate=2006-06-06+14%3A00
Bug 325465 seems to have caused this.

Vlad, could this be a regression from your patch?

Comment 6

[Remko de Keijzer]

Problem occurs also on Windows Vista
See 4d8a944e-ab45-40d5-a547-1918d2090706

Comment 7

[Vladimir Vukicevic [:vlad] [:vladv] (needinfo me, slow to respond)]

Could be, btu without knowing what flash is doing, I don't know how to say one way or the other.

Attachment: Test with simplified HTML

Henrik, the test case was on my site. See link of this bug.

I attached it also. But it does not contain the flash animation. I have no means to simplify that. It is important that is loaded outside the visible part and the wmode=transparant is also important.

By the way, I found this bug on the top crash sites. But those are from:
Firefox 3.1b2

There is no list for 3.5. Where should I report that?

Comment 9

[Charles]

Reproduced. Thanks for the sample URL.  Can you attach your SWF as well so I can have the whole package locally for testing?

Comment 10

[Henrik Skupin [:whimboo][⌚️UTC+2] (away 10/03 - 10/13)]

Attachment: swf file

Comment 11

[Henrik Skupin [:whimboo][⌚️UTC+2] (away 10/03 - 10/13)]

Attachment: testcase

This one uses the formerly uploaded swf file on Bugzilla.

I know but at this time it wasn't loading. So now we have both files online as a testcase.

[Charles]

Thank you.

[[:Cww]]

Per bug 503947 can users with this crash also say if they have the McAfee Site Advisor extension enabled and if disabling it helps with the crash?

This will help us write support articles with potential workarounds.

Comment 16

[u348128]

This bug is not related to McAfee, it is hard crasher.

Comment 17

[u348128]

Info from Jesse Ruderman:

Bug 502648 looks like a null deref, which is not exploitable.  See

for how I evaluate crash stacks.

The crashing hi5 site could be found from the top crash by URL:

Not sure who assigned the CVE, possibly based on the references in bug 503286.

Comment 20

[Charles]

Internal bug #2371949

Comment 21

[Johnny Stenback (:jst)]

For the record, this is triggerable with Firefox builds as old as 2007-01-01.

Comment 22

[Charles]

This is fixed in the latest release of Flash Player 10.0.32.18

Comment 23

[Johnny Stenback (:jst)]

Charles, I've got flash version 10.0.32.18 and I still see this crash when scrolling the testcase attached to this bug :(

Comment 24

[Charles]

Sorry had my build information crossed.  It will be fixed in our public beta later this year.

Comment 25

[Charles]

Public beta released.  This is now fixed.

[Marcia Knous [:marcia]]

Using Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 and Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2b4pre) Gecko/20091118 Namoroka/3.6b4pre I don't crash when scrolling the testcase. I am using Version: 10.1.51.45 Shockwave Flash 10.1 d51.

Comment 27

[Henrik Skupin [:whimboo][⌚️UTC+2] (away 10/03 - 10/13)]

Marcia, can you test it on Windows too? No comment on that bug mentioned that it happens on OS X too? Were you able to see it on OS X?

Comment 28

[Marcia Knous [:marcia]]

I tested on Win 7 with the updated flash plugin using Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2b4pre) Gecko/20091118 Namoroka/3.6b4pre (.NET CLR 3.5.30729). Will test on XP the next time I trek down to the lab.

[Henrik Skupin [:whimboo][⌚️UTC+2] (away 10/03 - 10/13)]

Works fine on XP too with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2b4pre) Gecko/20091118 Namoroka/3.6b4pre (.NET CLR 3.5.30729)

When do we close such bugs? Once the final release of the external application happened?

Comment 30

[Marcia Knous [:marcia]]

Tested on XP on the lab. Confirmed the crash with the older version of flash, then installed the new version and no crash using latest 1.9.2 nightly. I think we should wait until the final release of that version before we close the bug.

Comment 31

[Charles]

Close fixed if you don't mind.  While its a beta player its still an official release.

Comment 32

[u348128]

Crashes still with the crazyprofile.com:

bp-889d4358-c533-4943-aa30-f8ad22100210

Reopening based on latest comment. Charles can't you see the crash with Lucas version?
