  • Analysis of Microsoft “Patch Tuesday”
    Report 2015 Microsoft Vulnerabilities Study: Mitigating risk by removing user privileges Analysis of Microsoft “Patch Tuesday” Security Bulletins from 2015 highlights that 85% of Critical Microsoft vulnerabilities would be mitigated by removing admin rights across an enterprise, with a 52% increase in the total volume of vulnerabilities compared to 2014. avecto.com Report Contents Introduction 2 Methodology 2 Key findings 3 Vulnerability Categories 4 Microsoft Windows vulnerabilites 5 Internet Explorer 6 Microsoft Office 7 Windows Servers 8 Additional Microsoft services 9 Conclusion 9 About Avecto 11 Appendix 12 avecto.com 1 Report Introduction Compiled by Avecto, this report analyzes the data from security bulletins issued by Microsoft throughout 2015. Microsoft bulletins are typically issued on the second Tuesday of each month, a date commonly referred to as “Patch Tuesday”, and contain fixes for vulnerabilities affecting Microsoft products that have been discovered since the last bulletin’s release. Network administrators, Security Managers and IT Professionals then respond to the update as quickly as they are able, ensuring the patches are rolled out across their systems to protect against the known vulnerabilities. In 2015, it was widely reported that Microsoft’s Patch Tuesday approach would change for all Windows 10 devices, with an approach of patches being released as soon as they are available. This effectively increases response time by as much as a month, cutting down the time between a vulnerability being discovered (Zero Day) and the patch being rolled and applied. The 2015 Microsoft Vulnerabilities Report is the third iteration of Avecto’s research. In 2014, the same report found a total of 240 vulnerabilities with a Critical rating.

    Microsoft Patch Tuesday March 2019 Dear Constituents, Microsoft has released its monthly roll-up of security patches known as Second Patch Tuesday. This means it's time to get those security updates installed. The March 2019 software updates addresses a total of 64 security vulnerabilities in its Windows operating systems and other products, 17 of which are rated critical, 45 important, one moderate and one low in severity. Included in this month's update are fixes for two vulnerabilities that are known to be actively exploited in the wild. Security updates for two actively exploited vulnerabilities Google stated that a vulnerability in Chrome and in Windows 7 was being chained together and actively exploited in the wild. While this vulnerability was mitigated by security features of Windows 10, Google warned that Windows 7 users were at risk. This vulnerability, has been fixed as part of this month's Patch Tuesday. Finally, Microsoft also fixed two bugs that are reported to be publicly disclosed. The first is a Windows denial of service vulnerability and a vulnerability in the NuGet Package Manager. What to do Users and system administrators are strongly recommended to update to the latest security patches to protect your computer from security risks.

  • Windows Updates and Major Builds
    WINDOWS UPDATES AND MAJOR BUILDS Updates install automatically, and you can’t pick and choose Another big change with Window 10 is that there will be automatic updates, so there’s less chance of you missing an important security update or bug fix. In addition, all Windows 10 systems will be on the same page at all times, whether it’s on a computer, a tablet, or a smart phone. Visit the Windows Update interface (type windows update in the search box) and you’ll find a single button — Check for updates. Click this button and Windows will check for available updates. If it finds any, it will automatically download and install them. Windows will also check for updates in the background and automatically download and install them the moment that they are released by Microsoft. Unlike on previous versions of Windows, there’s no way to select individual updates you want to download. All updates — from security updates and Windows Defender definition updates to optional updates and driver updates — will be installed automatically. The only option you can control is to select the “Advanced options” link and uncheck Give me updates for other Microsoft products when I update Windows. This will allow you to disable updates for Microsoft Office and other Microsoft programs. In Windows 10, Microsoft is committed to rolling out both security updates and feature updates. Most of the installed Modern applications will also automatically update themselves via the Windows Store. Microsoft is thinking of Windows 10 as the last version of Windows, so instead of a Windows 11 or Windows 10.1, we should see future updates and interface changes appear on an ongoing basis.

    TLP- White1 Microsoft Patch Tuesday October 2019 Dear Constituents, Microsoft has released its monthly roll-up for the month of October with security patches known as Second Patch Tuesday. Microsoft has released security updates to fix a total of 59 vulnerabilities in Windows operating systems and related software, 9 of which are rated as critical, 49 are important, and one is moderate in severity. Two Critical Vulnerabilities for this month In this month's update two of the critical vulnerabilities patched this month are Remote Code Execution flaws in the VBScript engine, and both exist in the way VBScript handles objects in memory, allowing attackers to corrupt memory and execute arbitrary code in the context of the current user. These two vulnerabilities, tracked as CVE-2019-1238 and CVE-2019-1239, can be exploited remotely by tricking victims into visiting a specially crafted website through Internet Explorer. An attacker can also exploit these issues using an application or Microsoft Office document by embedding an ActiveX control marked ‘safe for initialization’ that utilizes Internet Explorer rendering engine. Other vulnerabilities patched by Microsoft this month on Microsoft products and services: Microsoft Windows Internet Explorer Microsoft Edge ChakraCore Microsoft Office, Office Services and Web Apps SQL Server Management Studio Open Source Software Microsoft Dynamics 365 Windows Update Assistant 1 CERT Tonga adopts the Traffic Light Protocol 1 Most of these vulnerabilities allow elevation of privilege, and some also
