Today Microsoft released patches to fix 94 vulnerabilities out of which 27 fix remote code execution issues which can allow an attackers to remotely take control of victim machines. This is a massive update and fixes more than double the number of vulnerabilities as compared to the last two months.
Hours before today’s Patch Tuesday release on the eve of May 8, Microsoft released an emergency updated to fix a vulnerability in their Malware Protection Engine. This critical vulnerability allows an attacker to take complete control of the victim’s machine by just sending an e-mail attachment. When the malware protection engine scans the attachment the malicious code in the file gets executed, allowing the attacker complete and full access to the computer. The attack can also be carried out by sending the file via an instant message or having the victim download the file from a website. It is absolutely essential that organizations using Microsoft Malware Protection Engine make sure that they are at version Version 1.1.13704.0 or later. Users should also check if they are patched for CVE-2017-0290, which was released for the same issue today.
In today’s Patch Tuesday update Microsoft released a total of 57 vulnerability fixes. Highest priority should go to patching 0-day issues which are actively exploited. On top of our list is the Office patch for CVE-2017-0261 which is triggered when a victim opens an Office file containing a malformed graphics image. The file could be delivered via email or any other means. As this is actively exploited in the wild and attackers can take complete control of the victim system, this should be treated with priority.
Microsoft Fixes 45 Vulnerabilities with new Security Update Guide – says goodbye to Security Bulletins
Today is the first month since 1998 in which Microsoft stopped releasing security bulletins with the familiar MSxx-xxx format and replaced it with the new security update guide. We talked about this change earlier in a few blog posts and finally today it’s time to say good bye to security bulletins which essentially combined related vulnerabilities and products for easy of consumption.
In today’s release Microsoft fixed a total of 45 vulnerabilities that could lead to remote code execution, denial-of-service, elevation of privileges, security feature bypass and spoofing. Top priority goes to the Office and WordPad CVE-2017-0199 which fixed a 0-day vulnerability that is being actively exploited in the wild. Exploitation of this vulnerability requires that a user open or preview a specially crafted file with an affected version of Office or WordPad. Attacker could accomplish this by sending a specially crafted file to the user and then convincing the user to open the file. We recommend administrators patch this as soon as possible.
Happy December! In this last Patch Tuesday installment for 2016, Microsoft released 12 security bulletins which brings the 2016 yearly count to 155. This is about 15% higher than last year. Out of more than 3 billion scans that Qualys performs each year we saw an increase of about 20% in the total number of Microsoft vulnerabilities. This increase can be attributed to an increase in the volume of scanning and to the 15% increase in number of Microsoft bulletins. But the year is not over and I will come up with the normalized number after the year ends.
Most organizations enforce system configuration policies to reduce the chance of misconfiguration and improve their overall security posture. For Microsoft Windows systems, many organizations rely on guidance from Microsoft Security Compliance Manager (SCM) for proper configuration. For organizations deploying Windows 10, this Top 5 list helps you understand and implement the new settings introduced in SCM for Windows 10.
As an engineer on the Qualys Policy Compliance product team, I routinely compare compliance benchmarks, and have compiled this list based on my work. If you are already familiar with previous version of Windows, this blog post can help you to quickly adopt the new changes.
Controls (represented by Control IDs or CIDs) are the building blocks of the policies in Qualys Policy Compliance used to measure and report compliance for a set of hosts. For each of the Top 5 in this article, we include the CID that allows you to build policies to measure and report compliance for that new setting.
It’s September 2016 Patch Tuesday, and Microsoft has released 14 security bulletins that affect a host of components including desktop operating systems, servers, browsers , Exchange server, Silverlight, SMBv1 and several others. It’s a large update that will keep desktop as well as server administrators busy. Seven updates are rated as critical, while the other seven are rated as important. One 0-day vulnerability CVE-2016-3352 which was publicly disclosed earlier is also patched in the MS16-110 bulletin.
Its July 2016 patch Tuesday and Microsoft has released 11 security updates that affect a host of desktop and server systems. Six updates are categorized as Critical while the rest are categorized as Important.
Most of the critical updates released today affect desktop systems. Top priority should be given to fixing browsers and Office which includes MS16-084 that affects Internet Explorer, MS16-085 which affects Microsoft Edge and MS16-088 for Office. All three updates fix vulnerabilities that allow an attacker to take complete control of the victim’s machine and therefore these should be patched immediately.
