Microsoft Patches 5 Zero-Day Vulnerabilities Being Exploited in the Wild

Microsoft has released its monthly Patch Tuesday update including a total of 10 security bulletin, and you are required to apply the whole package of patches altogether, whether you like it or not.

That’s because the company is kicking off a controversial new all-or-nothing patch model this month by packaging all security updates into a single payload, removing your ability to pick and choose which individual patches to install.

October’s patch bundle includes fixes for at least 5 separate dangerous zero-day vulnerabilities in Internet Explorer, Edge, Windows and Office products that attackers were already exploiting in the wild before the patch release.

The patches for these zero-day flaws are included in MS16-118, MS16-119, MS16-120, MS16-121 and MS16-126. All the zero-days are being exploited in the wild, allowing attackers to execute a remote command on victim’s system.

Although none of the zero-day flaws were publicly disclosed prior to Tuesday, the company was aware of attacks exploiting these flaws, said Microsoft.

Here’s the list of Zero-Day Vulnerabilities:

 

  1. CVE-2016-3298: An Internet Explorer zero-day flaw is a browser information disclosure vulnerability patched in MS16-118 bulletin among 11 other vulnerabilities. It could allow attackers to “test for the presence of files on disk.”
  2. CVE-2016-7189: A zero-day in the browser’s scripting engine has been patched in Microsoft Edge bulletin, MS16-119, among others. The flaw is a remote code execution vulnerability.
  3. CVE-2016-3393: Another zero-day in Microsoft Windows Graphics Component has been addressed in MS16-120 that could be exploited over the web, or via an email containing malicious file or over a file-sharing app to conduct RCE attack.
  4. CVE-2016-7193: A single zero-day in Office has been addressed in MS16-121 bulletin. The flaw is a remote code execution vulnerability caused by the way Office handles RTF files.
  5. CVE-2016-3298: The last publicly attacked zero-day has been patched in MS16-126, which is the only zero-day that is not rated critical, just moderate. The flaw is an information disclosure bug affecting Vista, Windows 7 and 8 and exists in the Microsoft Internet Messaging API.

Another bulletin rated critical is MS16-122 that patches a remote code execution flaw, CVE-2016-0142, in the Windows Video Control, affecting Windows Vista, 7, 8 and 10. The bug can be exploited when a user opens a crafted file or app from the web page or email.

Microsoft also patched twelve vulnerabilities in Adobe Flash Player for Windows 8.1, Windows 10, and Server 2012 in MS16-127.
