Google Fixes Major Gmail Bug Seven Hours After Exploit Details Go Public (zdnet.com) 39

Google has patched on Wednesday a major security bug impacting the Gmail and G Suite email servers. From a report: The bug could have allowed a threat actor to send spoofed emails mimicking any Gmail or G Suite customer. According to security researcher Allison Husain, who found and reported this issue to Google in April, the bug also allowed attachers to pass the spoofed emails as compliant with SPF (Sender Policy Framework) and DMARC (Domain-based Message Authentication, Reporting, and Conformance), two of the most advanced email security standards. However, despite having 137 days to fix the reported issue, Google initially delayed patches past the disclosure deadline, planning to fix the bug somewhere in September. Google engineers changed their mind yesterday after Husain published details about the bug on her blog, including proof-of-concept exploit code.

    Did Google comment on why they weren't more responsive on a fix? That seems like an egregiously long time to wait given all the active phishing gangs at work.

      Would you care if they did? Are you imagining a world where you'll get a candid, non-weasel worded explanation from Google?

      1999 called. They want their naive innocence back.

        It's almost like allowing Google to become a single point-of-failure for the Internet is a bad idea.

        I would even settle for a carefully worded article from ZDNet.

        The 90's also want their quality of reporting back.

        Well, if Google wants to give everyone a hard 90 day deadline before going public, then they should play by the same rules they impose on others, right?

        And things are even easier on Google. Unlike a flaw in a core OS component that requires tons of testing to make sure the fix doesn't cause regressions, a fix in Gmail is easy to test and deploy.

        So if Google can give Microsoft and Apple

          should

          Fantasy. Google doesn't care about "should." Maybe it once did. And maybe it occasionally pretends to now when convenient. But otherwise Google doesn't give fuck #1 about "should."

          Further, the fact the Google doesn't care isn't an actual problem. The problem is that anyone — individuals, regulators, law makers, competitors, etc. — were ever foolish enough to think it did, or that it would continue to do so, or that it ever did in the first place.

          Suckers all.

      Probably the same problem as any big org... the right people didn't know about it or didn't know how critical it was, they found out when it went public, and sent nasty e-mails internally demanding to know why this serious problem with Gmail hadn't been fixed in 137 days. Seven hours later it was fixed!

        The security researcher should have exploited the bug to send embarrassing company-wide messages posing as the CEO.

        That might have spurred them into action without the need to make the details public.

      A non-paranoid, non conspirationist option would be that deploying software updates is delayed until proper testing can be done. Gmail have *a lot* of users, and it's very probable not everyone even uses the same gmail, because of stuff like A/B testing and other complications that can arise with such a large architecture. Maintaining this mess usually isn't done in a "I see something bad, I fix it" fashion but more in a "we've got a batch of things to do, let's lump them together in a milestone" kind of way.
      Of course security issue should be treated faster, but it's also possible that Google used that to monitor who tried to abuse it. There's a large set of options that can explain the delay. The exploit being released for anyone to use makes is more important to fix now.
      That's a somewhat naive view on things, and the reality is probably more complex, but as a software developer I see some reasons to not deploy a fix ASAP. It's even possible the fix they deployed *now* is not the final one but only a quick mitigation.

        Oooh, I like your insidiuos thinking! Patch the bug, but leave a "fake" bug that makes it appear as though the bug is still present. Next, wait for them to exploit it and use the spoofed emails to identify the hacker. I love it! Finally, remove the "fake" bug once the exploit goes public.

        I doubt this is what happened, but it would be kinda cool if it was.

        • (also deep into conspiracy territory)

          I'd be more inclined to believe that an alphabet agency was already exploiting said bug and put pressure on Google not to fix it.

        It's a security issue, we've got to fix it!
        Is it critical?
        No, but it's pretty bad...

        Push it to tomorrow, we'll get to it after these critical issues are patched

        Months pass...

        It's a security issue - not too bad - but it's now published with proof of concept code!
        Damn it, OK today is it's lucky day.

      • stop making excuses for them, it is a really atrocious behaviour from them. They have critically lambasted other companies for similar slow responses and gone public with exploits. If they don't have processes in place to rapidly address security issues when reported then they have broken processes.
    • They are becoming more like the old Microsoft as time goes on
    • Google fixed the problem seven hours after it went public... For a delay, it's a small one.
  • Why is there no link to the blg post on tfa, but a zdnet artcle instead?

  • Amazing that they can fix something so fast and then ignore for most of the year the bug they introduced into the Pixel 3 line which frequently kills Bluetooth.

    • It's almost as if two entirely different engineering groups and specializations are involved in Gmail, and hardware support on a phone.

      What a shocker!

    • I have a launch day pixel 3 xl and never had any issues with bluetooth. I pair it every where I go, car, boat and headphones. /shrug

    I wonder if this was the cause of this morning's 7-hour G Suite outage.

  • Using the exploit to spam google perhaps would probably sped up the process?

  • If they were able to release the fix so quickly, they obviously had developed it ages ago, but not released it.

    I can think of only one reason why a company would delay the rollout of a security fix they had developed: A government they are in bed with wanted to use that security hole for its own purposes. Only once the exploit code was made public and it became a larger risk to common users did google release the fix they had been withholding at the orders of $gov.

      Not that I am terribly interested in such matters, but isn't CI/CD designed to get stuff pushed out to prod fast? And their fancy tooling like kubernetes designed for rapid updates/downgrades?

Trying to be happy is like trying to build a machine for which the only specification is that it should run noiselessly.

Working...
