UPDATE: Microsoft has announced that all updates will be delivered in the March 14 patch cycle.
As covered in our January blog, today Microsoft was supposed to scrap the existing system in which users used to get a bulletin like MS17-001 in favor of a new ‘single destination for security vulnerability information’ called the Security Updates Guide. But as per Microsoft’s blog, February’s Patch Tuesday has been delayed as Microsoft discovered a last minute issue that could impact some customers and could not resolve it in time for the planned update. This comes on the heels of the announcement that individual patches will not be available as they will be bundled together in the monthly Security update or monthly Cumulative update. If there is a problem in the patch for one kernel vulnerability for example, then all kernel or related vulnerabilities cannot be released as they are bundled together. A zero day SMB vulnerability was expected to be patched today and as of this writing there is no official statement on the new release date.
On the Adobe front, three security updated were released and the most important one is for Flash APSB17-04 which affects Windows, Mac, Linux and ChromeOS. If left un-patched this allows attackers to take complete control of the system. An attacker would host malicious flash content and the vulnerability will trigger when victim views the content.
