The reported issue "AVG: "Web TuneUP" extension multiple critical vulnerabilities" is fixed. The issue submitter, investigator, and closer is the same person, Tavis Ormandy.

As reported by Ormandy: "This isssue appears to be resolved in version 4.2.5.169 of the chrome extension, which looks like it's about to be made available for update on the webstore..." and then, a few days later: "I believe this issue is resolved now, but inline installations are disabled while the CWS team investigate possible policy violations.".

> It sounds to me like the following happened...

It's clear to me that that's not how it went down. From the bug report:

"This isssue appears to be resolved in version 4.2.5.169 of the chrome extension, which looks like it's about to be made available for update on the webstore..." (Emphasis mine)

How could Ormandy investigate and report on a new version of the software before it was uploaded to the Webstore, if AVG never sent it to him to evaluate, and he had to download it from the Web store to investigate it?

Pause for a moment and think about that. It's an important question.

After you've achieved enlightenment, remember that Tavis Ormandy is not some hack. Go do a bit of research on him and who he works for.

If you could stop condescending for a minute and pay attention to what I've said, you'll see the issue is still there. If you aren't convinced, just click http://webtuneup.avg.com/static/dist/app/4.0.5.0/interstitia... : as of the writing of this comment, that produces a javascript alert. Mind explaining how the issue was fixed?

It sounded like they did send it to him to evaluate, and it had only fixed the other issues. The XSS on AVG's website isn't something that can be fixed by the extension, it needs the audit, which clearly hasn't completed yet, or the link above wouldn't produce an alert.

Which specific part of the timeline do you differ from me on?

> If you could stop condescending for a minute...

I'm not condescending. I carefully read everything you wrote.

Carefully read Ormandy's report. Notice how the reported issue is:

"This extension adds numerous JavaScript API's to chrome... Anyway, many of the API's are broken, the attached exploit steals cookies from avg.com. It also exposes browsing history and other personal data to the internet, I wouldn't be surprised if it's possible to turn this into arbitrary code execution."

According to Ormandy, that issue is fixed. Or is your claim that he's lying about this and marking it as Resolved-Fixed just to get it off of his plate or something?

Talking about achieving enlightenment sounds condescending, and I wasn't sure how else to interpret it.

>Or is your claim that he's lying about this and marking it as Resolved-Fixed just to get it off of his plate or something?

The issue in 1 is fixed. The last issue in 5 is not. You can clearly look at the given link and see the issue is not resolved. Perhaps he didn't consider the XSS part of the core issue, only being mentioned in comment 5. Or maybe his anger at AVG clouded his judgement? I really shouldn't be trying to figure out why, it's sufficient to point out the what.

I guess you're not one for Zen koans and The Codeless Code, eh? Guess I'm getting old.

Ormandy's no hack. That didn't happen.

You can clearly look at the bug report and see that Mr. Ormandy thinks that the issue he reported is resolved. I don't know what you do for a living, but Ormandy does security research for a living. Have you looked into his credentials, reputation, and employer yet? :)

Like I said, I don't want to speculate on why he published it.

I'm aware this is for Google, and have mentioned that in comments in this thread. I'm not sure why I should believe his implication that everything was resolved over "my own lying eyes". Perhaps if he'd said "this XSS is not an issue" without explanation, I'd be happy, but he doesn't even acknowledge the point in what I can see.

Whether the bug report implies everything is resolved: I'm not so sure. Maybe he considers it resolved because every issue in the original was fixed, and AVG didn't acknowledge the last issue? I have no idea, and he hasn't given enough information for me to have an idea.

I'd sooner believe that something's wrong with the closing of the bug report than something's wrong with my understanding of how this is still a bug. Note that nobody yet has given me any explanation of how it might not be a bug, and HN is probably full of people who could explain it if it was the case.

Your credentials and ability in the field have not been established despite enquiries by many folks in this sub-thread. At the moment, I'm far more likely to believe that Mr. Ormandy has a far better understanding of the security issues with the AVG Chrome extension and their implications than you do.

> Perhaps if he'd said "this XSS is not an issue" without explanation, I'd be happy...

He marked the bug as Resolved-Fixed and removed the disclosure embargo. I don't know what more you want.

> Note that nobody yet has given me any explanation of how it might not be a bug...

tptacek and many others gave you a couple of really coherent replies in the subthread attached to your initial comment. None of them provide you with the answer you're looking for, but -frankly- you haven't demonstrated that you understand why it's reasonable the embargo on a security bug for a Chrome extension that AVG has made publicly available in the Chrome Webstore and that its security researcher (and -I suppose- AVG) feels fixes his reported problem was removed. :)

Maybe it'd help to know that the extension is currently not available pending an investigation into whether or not it violates any Webstore policies.

Occam's razor plays against you.
