This week's newsletter is all about the SSL 3.0 vulnerability that Google security researches recently discovered and which they affectionately named POODLE which stands for Padding Oracle On Downgraded Legacy Encryption. Although SSL 3.0 has been largely superseded by TLS 1.x, many web servers and web browsers automatically downgrade to SSL when negotiation of an encrypted HTTP session using TLS fails for some reason. Of course, just because something LOOKS like a poodle doesn't mean it ACTUALLY IS a poodle...as this Dilbert comic strip illustrates:
It must be embarrassing for a tough guy to style his hair like that.
Ask our Readers - Outlook PST file won't reattach
Last week in Issue #1002 More Shellshock for Windows admins a reader named Jim who is Chief of an IT group based in Pennsylvania, USA asked us the following:
We recently upgraded one of my users from Win7 Pro/Office 2007 to Win8 Pro/Office 2013 with a 'clean' install. When we went to restore his data, a problem arose. His PST file -- a whopping 4.4 GB -- would restore to the disk but couldn't be reattached to Outlook. We've restored the file to another Win7 Pro, equivalent to his old system, but have the same issue: "Corrupt File". We don't know if the issue was somehow caused during the backup process or if it is just too damn big. None of our usual repair tools, like ScanPST, will fix it -- most won't even open it because of the size.
- Any clever ways/tools to fix this problem?
- Any way to split the file into manageable chunks (even if have to we lose a few emails in the process)?
- And for my own edification… I thought that Office 2010 had removed the file size limitation on PST… True or false?
Jim later followed up saying he had found an answer to question 3 as follows:
By the way, I just read that Outlook 2007 increased the PST file size limit to 20GB and 2010 increased it again to 50GB.
We've received a ton of responses from our readers concerning Jim's questions. Obviously a lot of you have had experiences similar to Jim as you manage the Exchange/Outlook messaging infrastructure of your organization. Here is a selection of the responses we thought might be most helpful to the original poster:
Do you have Exchange Servers? Create a tempuser mailbox:
New-MailboxImportRequest tempuser -FilePath c:\temp\my.pst -AcceptLargeDataLoss -BadItemLimit 10000000
--from Keith, Exchange Engineer for a food services company
This issue was fixed in Office 2003 but the PST MUST be converted to Unicode. After conversion it must be repaired. The new size limit will now be 50Gb.
It is easiest to convert in place on the old system before migrating. I have done this many times. It is fairly quick.
--from a reader named James
There may be no way to fix the problem. A lot depends on where the original PST file was created.
If you upgraded from 2002 in the past and didn't convert the PST to the new file type then the file is larger than the maximum file size for the older structure can handle. If so then you are probably hosed.
However there may be away around this:
- In your new outlook 2013 create a new PST file (when you add a new account it will create a new PST file).
- Once you have done this go to "File" then "Open" and select "Import" then "Import from another program or file".
- Click "Next" then select Outlook data file (PST) from the options and then "Next".
- Locate your file and let it proceed to import.
This may work but if the file is too large it may fail at some point.
--from a reader named John
There are a couple possibilities:
- This 4.4GB limit sounds over the 3 GB paging file limit of 32-bit Windows systems. Are they installing the 64-bit version of MS Outlook (and MS Office, for that matter) on the recipient system, or using the 32-bit version of MS Office?
- Are you sure that both the backup system used and the destination system supports files larger than about 3 GB? Maybe your backup system already messed up his .pst file.
--from a reader named Luis
There is a great utility Kroll OnTrack EasyRecovery Pro that repairs .pst files. I have used it for many years:
--Howard, Network Administrator for an architectural firm
I got similar issue before. Just add physical memory then it works. For your reference and hope it helps.
--from a reader named Ching
One question comes to mind. Where is the .pst file stored, locally or on a network share? PST files on a network share are not supported any more and will show this symptom.
--from a reader named Lyle
This problem has been caused in our environment if the file was backed up while MS Communicator/Lync was still running on the user's PC.
--from a reader named Barry
Just wondering if they reattached the PST file by using the import feature or did they just stick it into the APP Data/Local folder hoping it would find and attach itself?--from a reader named Tom
Ask our Readers - CloudMark
Also in last week's issue was the following request we received from reader who works at an ISP in the eastern USA:
Hi, one of our readers asked us what we knew about CloudMark and which ISPs use it. Knowing virtually nothing about such things, we thought maybe you can help her. THX.
So far we've received two responses from our newsletter readers to the above request:
Just read the call out for feedback on Cloudmark in the 10/20 issue of WServerNews. I have been using Cloudmark -- both the Desktop and Exchange versions for years. I am, however, an end-user, not an ISP. So, I have no idea if this is going to help the reader who made this query, but the one thing I can tell you with absolute certainty is that you will not find a more accurate spam filter. And by accurate, I mean not only identifying spam, but also *not* identifying legitimate e-mails as spam (false positives).
I recently decided it was time to upgrade to an actual spam-filtering appliance and we installed a Barracuda Spam & Virus Firewall Model 200. Barracuda is undeniably a high-end product. My experience, however, is that it doesn't hold a candle to Cloudmark when it comes to false positives. Hope this is helpful.
--from Stewart, President of a hardware company
We've been experimenting with fighting SPAM at the desktop level. This free product is very very good at getting what our Symantec Filters cannot and it lets you mark them. You can download it here from their website:

And now on to the main topic of this week's issue...
POODLE for Windows admins
Things just seem to keep getting worse in IT, don't they? Just when you thought you had a handle on the ShellShock vulnerability a.k.a. BASH bug, another gaping flaw in the underlying protocols of the Internet raises its nasty head. So what is POODLE? Why should we worry about it? Can it affect Windows-based environments? If so, what can we do about it?
What is POODLE?
It's basically a flaw in version 3.0 of the SSL protocol which used to be the standard for encrypting web traffic but has since been superseded by an updated protocol named TLS.
Should I be worried?
If your company or organization does business over the web then you should probably be worried for two reasons. First, while your web servers are likely configured to use TLS by default for encrypting web traffic, they are also likely configured to fall back to using SSL 3.0 should negotiation between your web server and a customer's web browser fail with TLS for some reason. Second, if your users need to securely connect with their web browsers to any web servers that are outside your control, those web servers are vulnerable for the same reason described above. And if those web servers beyond your control get compromised, then users connecting to them are potentially exposed to various kinds of information disclosure attacks.
I want to know more about POODLE
Want to learn more about how POODLE works? Here is the original announcement concerning this vulnerability on the Google Online Security Blog:
The above blog post references a security advisory published on OpenSSL.org by some members of the Google Security Team (PDF file):
StackExchange also has an excellent "in a nutshell" explanation of how POODLE works:
OK what should I do?
There are basically two things you can do to protect your assets against POODLE:
- Disable SSL 3.0 on all systems, platforms, and products you own and manage.
- Apply any patches released by vendors to address this vulnerability.
What about Microsoft products?
SSL 3.0 is still supported (available for fallback purposes) in the following Microsoft products:
- All versions of the Windows operating system including both client and server versions
- Internet Information Services (IIS) web server role on the Windows Server platform
- Internet Explorer web browser on all versions of Windows
Yikes! OK how can I disable SSL 3.0 on Microsoft products?
See the Suggested Actions section of Microsoft Security Advisory 3009008 for some general workarounds (requires Windows ID sign-in):
This thread on ServerFault may also be helpful especially with regard to IIS:
And this tweet by Microsoft MVP Eric Lawrence shows an easy way users can disable SSL 3.0 if they use Internet Explorer as their web browser:
Eric later followed this up with another tweet:
What about other web servers and web browsers?
Scott Helme has a terrific post on his blog describing how to disable SSL 3.0 on:
- Web servers like Apache, NginX, and IIS
- Web browsers like Firefox, Chrome and Internet Explorer
Here is Scott's post:
Scott's article also includes links to sites where you can test your web server or web browser to ensure they have SSL 3.0 disabled.
George Chetcuti also published a note about the POODLE exploit on his blog on WindowsSecurity.com:
At the end of George's note he says "Go here to find out how to disable SSLv3 support in your browser" and points you to another good article that describes how to disable SSLv3 on various browser platforms:
Anything more for Windows admins?
We've found a few threads on various Microsoft forums that you might want to keep an eye on:

Tip of the Week - Update for Windows 7 (32-bit) (KB2952664) FAILED
This week's tip has been contributed by Hubert Heller who manages the Flixxy.com site that has the fun videos we include in the FAVE Links section of our newsletter:
Update for Windows 7 (32-bit) (KB2952664) FAILED
Just in case it happens to you (as it did to me and a friend of mine who also uses Windows 7), here is the fix. During my Windows update I received the above error message while attempting the Update for Windows 7 (KB2952664). I had to do this step to re-install:
Go to Windows update then click on View update history then click on Installed updates, search for the failed kb number and double click on it and it will prompt to uninstall. Uninstall then reboot and go back to Windows update and click Check for updates it should come up and re-download and install.
I hope this works for you. See here for more:
How can a company like Microsoft let this go through?
How indeed? I've actually become more concerned lately about the quality control Microsoft exercises over their update release process and have begun advising my family and friends to changed the Windows Update settings on their PCs from "Install updates automatically (Recommended)" to "Download updates but let me choose whether to install them." Then I tell them that when the Windows Update popup appears in their taskbar notification area, they should wait a week and haunt the Microsoft Answers forums to see whether any problems have been discovered with the newly released updates before they go ahead and install the updates on their PCs.
