Question

Site failing starting 9/21 with new Chrome and new Flash updates - PLEASE HELP!

I have a vertical site for boating with 110,000 users.  The main part of the site is based around a 400KB swf that is mostly AS3.  It has worked flawlessly for years.  I haven't updated it in about 4 months.  There has been no server update that would be causing any issues at all in at least a month.

All of a sudden on 9/21, some users started complaining that the main map view was all white.  Other things are not working correctly either.  It happened mostly with users who had automatic updates turned on in Google Chrome.  I understand that a new Flash version was auto-installed as a part of a Google update yesterday.

I went to the Adobe Flash page and was prompted to update my player although I have 10.3.183.10 installed.  I didn't do that.

Today people on other platforms are complaining that they're getting the same white screen although the bulk of our users are having no problems, probably because they haven't been updated.  It seems to happen in Internet Explorer and Firefox starting today.  I have a feeling these people had their Flash version updated.

I updated to the beta v11 and now I'm experiencing the white screen blank problem - it is perfectly reproducible.

To view the place where this is happening, go to:

https://activecaptain.com/X.php

The problem occurs on both OSX and Windows.  I don't think it is operating system involved at all.

There are no errors, warnings, messages, traces, etc. coming out on the developer windows in Safari in v11.  Absolutely everything appears perfect except it isn't working at all.

This is causing a major problem and I don't know what to do.

    Hi JeffActive,

    Sorry for all the inconvenience you encountered so far.

    We did investigation on your problem and found out it's related with our security update on 9/21/2011.

    When load your website with debugger plugin player, the following stack overflow errors are found:

    AS error occurred:

    Error: Error #1023: Stack overflow occurred.

                    at com.afcomponents.umap.gui::UIMapControl/getClassByName()

                    at com.afcomponents.umap.gui::UIMapControl/getClassByName()

                                    ….

                    at com.afcomponents.umap.gui::UIMapControl/getClassByName()

    This haven't been seen in flash player no later than 10,3,183,7.

    By confirming with our developers, in 10,3,183,10, we added some checks to detect stack overflow conditions. That's why 'Stack Overflow Occurred' errors are detected in your codes.

    If go to below security bulletin page, you can find more detailed information of security updates in 10,3,183,10:

    http://www.adobe.com/support/security/bulletins/apsb11-26.html

    As there are stack overflow errors in your codes, flash player(later than 10,3,183,10) avoids loading it. To fix the problem, need to fix those AS stack overflow errors in your codes.

    We don't have the source code of your swf file right now, so can't tell which AS codes cause this stack overflow issue. Could you test your swf file in our latest debugger player(10,3,183,10), then find out which lines of AS codes caused the problem? Once the stack overflow issue is solved, the swf should be loaded correctly.

    Again, sorry for all the inconvenience cause by this new security changes. We're improving our player to be more secure. We would be glad to work with you to solve your problem ASAP if any help needed from us.

    Thanks,

    Yan

    Thanks Yan.

    The component that it occurs in is UMap and it hasn't really been available for a year or so.  I'm in contact with the owner of the code but I'm not sure the source even exists any longer.

    Is there any way to have the stack overflow treated in a similar way (ignored) as previous versions?

    Hi JeffActive,

    Thanks for repsonding so quickly!

    Is it http://www.afcomponents.com/tutorials/umap_as3/ the same 'UMap' that you mentioned?

    'Is there any way to have the stack overflow treated in a similar way (ignored) as previous versions?'

    Answer: I'm afraid not. Sorry about that.... We improved our player to be more safer.

    I'm also looking for a fix for your problem right now, but is stuck by lacking of source codes. That would be great if there's a source codes provided. Will keep update with you.

    Thanks!

    Yan

    Chris, thanks.

    I added to bugbase.  When I submitted the bug I got:

    Thank you for submitting a bug. Due to security concerns, this bug will not be externally viewable.

    So I'm not really sure how to post back here with a URL for the bug.  Did I miss something?

    No, it sounds like you made this a crash issue which will make the bug invisible from public view.  We'll be contacting you shortly, if you haven't been already.

    Thanks,

    Chris
