Microsoft releases 14 patches for Windows

bug-162019

Microsoft released patches for 14 vulnerabilities in its Windows operating system, Office and Internet Explorer software on Tuesday, including four it deemed critical, it’s highest severity rating.

All four of the critical bugs could allow attackers to remotely execute programs on a targeted system, something that in the past has allowed hackers to steal personal information such as passwords or take over machines for the purpose of sending spam.

The patches were released as part of the company’s monthly “patch Tuesdaysecurity update for its major software products. The company had originally planned to deliver 16 updates Tuesday, but two are marked as yet to appear. They include one that was expected to carry a critical rating.

At 14, the number of patches is a monthly record for 2013 and 2014.

They include a problem with Windows Object Linking and Embedding that could allow remote code execution if the user visits a website containing malicious code. If the user is logged in as the administrator, the attacker could gain the ability to install programs and change and delete data. A related patch for Internet Explorer fixes the vulnerability with malicious websites and 16 other problems with the software, said Microsoft.

A security update for the Microsoft Secure Channel software in Windows fixes a problem that leaves Windows Server vulnerable to attack from specially crafted packets. The fourth critical patch fixes a hole in Windows that allows attackers to invoke Microsoft XML Core Services from a malicious website and then remotely execute code on a target system.

A further seven patches are marked as important—the second highest rank.

One vulnerability in Microsoft Office allows for remote execution of code, four additional problems allow attackers to assign themselves higher privileges and two allow bypass of certain security features in Windows.

Microsoft Patch Tuesday tackles three critical vulnerabilities, including ‘Sandworm’ | PCWorld

After a relatively quiet few months, Microsoft Patch Tuesday is back in full force, covering three zero-day vulnerabilities that administrators should attend to as quickly as possible.

Microsoft issued eight security bulletins Tuesday, covering a total of 24 vulnerabilities found in Windows, Internet Explorer, Office and the .Net framework. Three of the bulletins are marked as critical, which means administrators should test and apply these patches immediately. A single bulletin can cover multiple vulnerabilities within one technology.

Three of these vulnerabilities are already being exploited by malicious attackers, hence they are being called zero-day vulnerabilities. This is the first time in recent history—and perhaps ever—that Microsoft has fixed three zero-day vulnerabilities in a single round of patches, which Microsoft typically issues on the second Tuesday of each month.

“Sandworm” is the most notorious of the three and is a vulnerability in Microsoft Windows that has already been used in attacks on NATO and a number of European government agencies, telecommunication firms and energy companies, according to cyberthreat intelligence firm iSight. Microsoft Bulletin MS14-060 fixes this bug.

“This is an urgent one to fix,” said Wolfgang Kandek, chief technology officer for IT security firm Qualys.

Microsoft marked MS14-060 as important rather than critical because for the attack to work, it would require a user to click on a file. Qualys ranks this vulnerability as more severe in that it is pretty easy to trick a single person into clicking on a file, such as a PowerPoint presentation, which would be all that would be required for an attacker to gain access to an internal network with a well-crafted script, Kandek said.

Sandworm is a good reminder for administrators to make sure that they set the user permissions correctly on desktop and laptop computers, meaning not to give an end user full administrative privileges on the machine, Kandek said.

Internet Explorer gets patched, too

The second zero-day flaw addresses a problem in Internet Explorer and the fix is found in MS14-056. This vulnerability “could allow an attacker to break out of the sandboxing capabilities in Internet Explorer,” said Amol Sarwate, director of vulnerability research at Qualys.

The third zero-day, addressed in MS14-058, also comes from a flaw within Windows, namely from the way the operating system kernel drivers handle TrueType fonts. An attacker could embed some malicious code within a TrueType font. When a user visits a site with these ill fonts, Windows will download the font package and automatically execute the code buried within.

Beyond Microsoft’s patches, administrators will also have a busy week with patches from Adobe and Oracle, Kandek said.

On Tuesday, Adobe released a set of patches for its Flash multimedia player. Oracle is also releasing a wide range of patches for its enterprise software. In particular, administrators should take a look at the Java patches, Kandek advised.

Dialog boxes may be killing Internet Explorer

Internet Explorer running slow? Dialog boxes could be at fault

Internet Explorer running slow? Dialog boxes could be at fault | PCWorld

 

If you’ve noticed Internet Explorer running slowly lately—or just halting altogether—here’s one possible cause: dialog boxes.

On Friday, the same day that Microsoft recommended users download the latest updates for Windows 7 and 8, Microsoft issued a hotfix for Internet Explorer. According to asupport article issued Friday, “web applications that implement consecutive modal dialog boxes may cause Internet Explorer to become slow and unresponsive over time.”

Microsoft issued the hotfix for Internet Explorer versions 7 through 11—basically every major version.

Microsoft pulls update after crashes

Microsoft pulls update

People often ask me why I recommend disabling Automatic updates in Windows. Well here’s one reason…

Apparently this update has been causing crashes and slowdowns. So if you have automatic updates turned on and your PC just recently started acting unbecomingly, this might be the problem.

“Microsoft said that it had discovered three issues with the updates associated with its August updates last week (specifically updates 298279129702282975719, and 297533), otherwise known as the security and feature updates that began rolling out on August 2.”

“Microsoft recommends that customers uninstall this update. As an added precaution, Microsoft has removed the download links to the 2982791 security update.”

Not quite as easy as it might seem. It seems you need to tinker with the registry, which can completely brick your PC if you don’t know what you’re doing.

As a humorous side note, if you are still running Windows XP, you don’t have to worry at all!

XP Support is Dead So Now What?

Windows XP Support is Dead So Now What?

Now what should I do?
What happens if I don’t upgrade?
Is there a way around being forced to upgrade?

xp-bug-162019

All good questions. Here’s the deal and what it means to you.

Microsoft has dropped support for XP. This means a a lot of things, but few things in particular stand out:

1) No new updates. No security fixes. No service packs. Basically you are on your own against every new threat. I have seen a couple registry hacks which supposedly can restore your Updates, but since none of them are being tested actively on Windows XP before release, you can be sure that your “unsupported system” will eventually…or sooner…fail to work properly. Updates are a good thing.
2) No new versions of Internet Explorer. You are stuck on IE 8 until the end of time. IE 8 doesn’t support many newer web protocols already, and the list of sites that don’t work with IE 8 will only keep growing. You may or may not be able to get around this by using Chrome or Firefox, but there still many websites which only support IE, many of which are already requiring IE 9 and above.
3) Software incompatibilities with 3rd party vendors will grow. Already many new titles are Windows 7/8 only, and upgrades to existing non-Microsoft programs will quickly stop supporting WIndows XP if they haven’t already. Newer versions of Microsoft Office already support only Windows 7 and up. That means you’ll be forced to upgrade eventually anyway so that you can use the latest versions of your favorite software.  And by eventually, I mean probably soon.

There are a whole lot of other things I’m sure I haven’t mentioned, but the bottom line is that if you don’t upgrade, your security will be reduced and your risk increased.  Certainly everyone’s situation will vary, and the degree of risk can be reduced with some simple (or not so simple) changes, but any way you slice it, Microsoft is saying, “Upgrade, or we can’t be responsible for what happens”.  Sounds just a bit too much like paying protection to the Mob to stay in business.

But even though Microsoft has mandated that you MUST upgrade (and NOW), there may be reasons you aren’t quite ready to replace EVERY Windows XP system in your office TODAY. You may be locked into using an older software title which won’t run on newer Windows versions. Or perhaps budget constraints are preventing you from upgrading all your systems immediately. Or…here’s a novel thought…your computers may be working just fine for what you need them to do, and you don’t see why you need to waste money on new PCs right now.

I think there’s a good reason to feel that way. Nobody likes being strong-armed into purchase decisions, and it’s easy to look at the negative side of the new  “offer-you-can’t-refuse” style of marketing Microsoft is taking here. But there is another side of this story…Windows XP is about 15 years old, and the harsh truth is that upgrading will improve compatibility and performance, in addition to the improved security. While there are numerous ways to work around the security issues created by the lack of ongoing updates, you will be far better off for the upgrade in the long run because of performance enhancements and improved compatibility.

So, our bottom line recommendation is:

Upgrade to Windows 7 as soon as you can. Hardware improvements and 64 Bit computing mean huge performance boosts and best compatibility with the latest software titles. We feel that 64 BIT computing is a must for performance, as 32 BIT systems are limited to 4 GB of RAM.

Move your office as quickly as possible to a 100% Windows 7/8 environment. We are still recommending Windows 7 64 Bit for most business situations, rather than Windows 8, due to software compatibility concerns, Windows 8 also represents a large learning curve due to significant operating system changes between Windows 7 and 8.  We recommend Microsoft Windows 7 64 Bit Professional with Service Pack 1.

Phase in your upgrades as quickly as you can. On systems which are stuck on XP, lock down IE 8 and force users to use Chrome or Firefox. That single step will reduce your security threat immensely. Also, if you must run XP for some reason, consider running in a virtualized environment if possible. XP running on a HyperV server can be much easier to secure. It also facilitates shared access which can be helpful for infrequently used legacy applications which must be maintained.

Staying on XP for a little while may make sense, but don’t expect to run those old systems forever without putting your data, network,  and possibly your entire company at risk. Running on an unsupported OS means trouble, and the longer you hold out, the more the risk increases. It doesn’t have to be today, but don’t wait until you have problems…they may be much bigger than you expect.

“This release is somewhat notable as it underscores Microsoft’s faster release strategy for non-numbered releases, which is to say smaller, incremental updates rather than platform-wide releases. If you use a Windows machine, in other words, you can expect your machine to improve month-by-month”.
