Fun with the fuzzer

, , ,

Yesterday Mozilla released their jsfunfuzz tool at the Blackhat convention in Las Vegas. The tool is very useful for stress-testing the javascript engine and its stability. While running the tool, we found four crashers - one of which might have some security implications.

Here is a build that should address all of the issues: test it, give it a spin with the tool - and please report any crashers you might find with the fuzzer, and most importantly: send us a crashlog along with it!

Have fuzz fun! And many thanks to Mozilla for sharing their tool.

As long Opera doesn't offer it officialy, version 9.23 isn't final and isn't out there to pick it up.

I must agree with xErath the current Final version is 9.22

rseiler 8. August 2007, 18:43

Let's call it the de facto final then. In my memory, it's been at least a year since what's been put on the FTP server has been pulled for retooling.

What's curious, however, is how Opera rarely likes testing their final RC build externally HERE. You would think this would be the place to alert people about it, rather than dribbling it out silently on FTP. Why have this blog at all then?

Oh come on!

True. Maybe we should close it. After all, does anybody care about Kestrel? p:

FataL 8. August 2007, 18:53

BTW, I found one more regression bug (JavaScript, DOM): setting input type erases its value. P:

It happened once, so it could happen again.

But we tested 9.23! There were 2 builds since the build we tested (8805 vs 8807). That's truly nothing.

One build (and as little as one extra or one missing character) can turn stable software into a crashing or non-starting mess. (Speaking from experience)

I agree 9.22 is the latest until it becomes publicly available for download from the normal public location of opera.com/download.

EDIT: Any chance you could edit it instead of deleting my whole post?
Will Opera devs get their posts removed for mentioning kestrel that which we do not speak of TM as well? Its like watching an action flick. What will happen? Thats on topic with the current events (in the comments) of this blog post.

olli 8. August 2007, 19:54

fearphage: No we will not remove csant's post, but rest asured we will find another way to punish him

fearphage 8. August 2007, 20:02

Might I suggest flogging? :lol:

kyleabaker 8. August 2007, 20:08

@olli
No need for punishment. :wink: We're all excited about the K****** builds. And I have to agree with the others. 9.22 is the current recommended version until the devs feel it is safe and ready to release a newer one (I am assuming tomorrow since it was mentioned earlier), so what is on the server really means nothing until it is announced. I for one am glad that this blog has not been closed. :D This is my most visited blog of all time, hehe. Always nice to hear some news and see what everyone is talking about (when it is on topic mind you).

@Fatal
I can confirm the bug (Vista x64), however, I'm unable to confirm that it is a regression or not as I have not tested this in previous builds. Did you file a report?

NoteMe 8. August 2007, 20:09

Sig. Santambrogio now have to wash dishes until Monday, so no more bug reports will be accepted at this time p:

for at least the last three finals, it has been anywhere *other* than the homepage or forum.... any excuse...

does anybody care about Kestrel?

yes!! we are keeping quiet about it, to stop the hunger pangs... :frown:

Sure, but it doesn't warrant a full end-user testing cycle either. If that extra character causes a major mess, people that download directly from the FTP will notice very quickly and it won't ever hit the opera.com/download page (like last year).

Junyor 8. August 2007, 20:48

The 9.23 builds that appeared on the FTP server today are being pulled due to an issue with Widgets.

SirJeff 8. August 2007, 21:06

haha I was reading about jsfunfuzz and MemGuard .... and Opera crashed P: (btw build 8800 winxpsp2) guess i should install MemGuard and build 8805 now!

illiad 8. August 2007, 21:39

the new fix is out .. see if it makes Vista 'play nicer' ..:smile:

More infos on this issue?

Thanks

hansbendiksen 8. August 2007, 22:34

I just discovered a strange behaviour in the 9.23 build 8805.

In the tools -> apperence menu under "panels". In the drop down menu for the panelplacement the marking jumps to "off" randomly. Is this just on my system?

I'm using Vista 32 bit with the latest hotfixes from MS.

Maybe this is an easteregg? :jester:

Ps.

@illiad: The fixes from MS did not do wonders with Opera for me. Still got the infamous CPU issue... :furious:

Known problem. This was a hard to reproduce issue, but eventually it was fixed (you will have to wait for Kestrel though to see the fix).

Junyor 8. August 2007, 23:05

@Darken: Sorry, that's all the information we'll be providing for now.

Darken 9. August 2007, 00:07

@Junyor: Safe to use this build without drastic/major problem? Because, for now, I don't have any problem with this build installed on my PCs.

New issue.

Try expanding the categories [+] on dell's driver downloads. Not working for me. http://support.dell.com/support/downloads/driverslist.aspx?os=WLH&osl=EN&catid=-1&impid=-1&servicetag=&SystemID=XPS_M1710&hidos=WW1&hidlang=en

This used to work just fine. I don't know if Dell has done som changes to their website, or if it's Opera 9.23/9.22...

@ Rijk: Okey. :smile:

@ JoRgE-1987: Same issue here...
Who is google hireing these days? Not so skilled web developers, I'm afraid.

odolisk 9. August 2007, 08:25

to hansbendiksen:
(sorry for my ugly english)
If i set "Identify as Opera" site on your link don't allow to expand the categories. But if i set "Identify as Firefox" - all work. My conclusion: Dell makes different pages for Opera and for FF..

hansbendiksen 9. August 2007, 08:41

@ odolisk: Yep, you're right. A classic software racism issue. When will the world learn? Can't we all just get along? :psmurf:

NoteMe 9. August 2007, 08:52

Looking at Dells code, it looks like they only know about IE and "other" browsers.

I've dowloaded 9.23 build 8807 from:
ftp://ftp.opera.com/pub/opera/win/923/int/

I installed it, but now the FTP server has cancelled the directory named "923"!

Why?
There were problems with that build?

NoteMe 9. August 2007, 09:56

@Same76,

Look at Junyors post:

olli 9. August 2007, 12:33

Guys we pulled the build as we haad to look into some anomalies, it might seem like the issue was not with Opera rather with the widgets.. The bittorrent widget has been removed as it doesn't work..
We might still release this build, but we don't want to take any chances so we are testing abit more :-)

*Better safe then sorry*

lamarca: No we are still testing 8807 :-)

lamarca 9. August 2007, 12:53

thanks, olli.

Hi,

I found a bug a few versions ago:
http://img444.imageshack.us/img444/1121/zrzutekranuof2.png

A 'window with errors on a page' popups in the wrong login window.

haavard 16. August 2007, 14:02

Is that related to the JS fuzzer, jarpiw?
