Adobe Patches Flash but Delays Reader Update

Summary:

  • This vulnerability affects: Adobe Flash Player running on all platforms and Adobe Air
  • How an attacker exploits it: By enticing users to visit a website containing malicious Flash content
  • Impact: In the worst case, an attacker can execute code on the user’s computer, potentially gaining control of it
  • What to do: Download and install the latest version of Adobe Flash Player for your platform

Exposure:

Adobe Flash Player displays interactive, animated web content called Flash. Although Flash is optional, 99% of PC users download and install it to view multimedia web content. It runs on many operating systems, including mobile operating systems like Android.

In a security bulletin released this week during Patch Day, Adobe released an update that fixes a dozen security vulnerabilities affecting Flash Player running on any platform. The bulletin doesn’t describe the flaws in much technical detail, but does say most of them consist of various types of memory corruption flaws. If an attacker can entice one of your users to visit a malicious website containing specially crafted Flash content, he could exploit many of these vulnerabilities to execute code on that user’s computer, with that user’s privileges. If your Windows users have local administrator privileges, an attacker could exploit this flaw to gain full control of their PCs.

Though attackers aren’t exploiting these flaws in the wild yet, Adobe rates them as a “Priority 1” issues for Windows, Mac, and Linux users, and recommends you apply the updates within 72 hours. These vulnerabilities also affect other platforms as well, though not as severely. I recommend you update any Flash capable device as soon as you can.

As an aside, though Adobe promised a Reader update this month, they seem to have delayed it for some reason. You may want to keep an eye on Adobe’s Security page for more updates.

Solution Path

Adobe has released new versions of Flash Player to fix these issues. If you allow Adobe Flash in your network, you should download and install the new versions immediately. If you’ve enabled Flash Player’s recent “silent update” option, you will receive this update automatically.

You can download Flash for your computer at the link provided below. See the bulletin’s “Affected Software” section for more details on getting Flash updates for other platforms:

Keep in mind, if you use Google Chrome or Internet Explorer 10 or 11 you’ll have to update it separately.

For All WatchGuard Users:

If you choose, you can configure the HTTP proxy on your XTM appliance to block Flash content. Keep in mind, doing so blocks all Flash content, whether legitimate or malicious.

Our proxies offer many ways for you to block files and content, including by file extensionMIME type, or by using very specific hexidecimal patterns found in the body of a message – a technique sometimes referred to as Magic Byte detection. Below I list the various ways you can identify various Flash files:

File Extension:

  • .flv –  Adobe Flash file (file typically used on websites)
  • .fla – Flash movie file
  • .f4v – Flash video file
  • .f4p – Protected Flash video file
  • .f4a – Flash audio file
  • .f4b – Flash audiobook file

MIME types:

  • video/x-flv
  • video/mp4 (used for more than just Flash)
  • audio/mp4 (used for more than just Flash)

FILExt.com reported Magic Byte Pattern:

  • Hex FLV: 46 4C 56 01
  • ASCII FLV: FLV
  • Hex FLA:  D0 CF 11 E0 A1 B1 1A E1 00

(Keep in mind, not all the Hex and ASCII patterns shared here are appropriate for content blocking. If the pattern is too short, or not unique enough, blocking with them could result in many false positives) 

If you decide you want to block Flash files, the links below contain instructions that will help you configure your Firebox proxy’s content blocking features using the file and MIME information listed above.

Status:

Adobe has released updates to fix these Flash vulnerabilities.

Microsoft Black Tuesday: Windows, IE, Lync, and .NET Patches

As you may know, today was Microsoft Patch Day. If you manage a Windows-based network, it’s time to get the latest updates.

According to Microsoft’s summary post, the Redmond-based software company released four security bulletins fixing 41 vulnerabilities in many of their popular products. The affected software includes, Windows, Internet Explorer (IE), Lync Server, and the .NET Framework. Microsoft rates the IE update as Critical, and the rest as Important.

As you might guess from the severity ratings, the IE update is the most important. It fixes over 37 security flaws in the popular browser, many of which attackers could use in drive-by download attacks (where just visiting a web site results in malware on your computer). Furthermore, one of the fixes closes a zero day vulnerability that attackers have exploited in the wild. If you use IE, I recommend you apply its update as quickly as your can. You should also install the other updates as well, however, their mitigating factors lessen their risk, so you can install them at your convenience.

In summary, if you use any of the affected products, download, test, and deploy these updates as quickly as you can or let Windows’ Automatic Update do it for you. For the server related updates, I highly recommend you test them before installing them on production servers, as Microsoft has released a few problem causing updates recently. You can find more information about these bulletins and updates in Microsoft’s September Summary advisory.

Also note today is Adobe’s Patch Day as well, and they released one security update fixing 12 vulnerabilities in Flash Player. If you use Flash, you should update it quickly. Adobe also pre-announced a Reader update earlier this month. However, it appears they have had to delay the update for some reason.

I’ll share more details about today’s patches on the blog throughout the day. However, I am traveling internationally, so the updates may not arrive as regularly as usual. If you are in a hurry to patch, I recommend you visit the links above, and start now.  — Corey Nachreiner, CISSP (@SecAdept).

Celeb Selfie Hack – WSWiR Episode 120

Software Patches, Home Depot Breach, and Celebrity Selfie Hack

If you need a quick source for all your information security (infosec) news, you’ve come to the right place. I summarize the most important infosec news in this weekly video, and provide links to other security stories as well.

Unfortunately, today’s episode includes a pretty creepy hack. The show covers next week’s upcoming software patches, another credit card leak that seems to come from Home Depot, and a gross story about hackers stealing hundreds of celebrities’ most private pictures. Find the details in the video below and see what you can learn from these unfortunate cyber attacks.

As always, check the Reference section if you are interested in other stories that I didn’t cover in the video. Also, I will be traveling the next few weeks, which means I may not be able to post this video as regularly as usual. Expect the video to turn up at irregular times, otherwise I may post a written version of the weekly summary instead. Have a great weekend, and stay safe online!
