Hyper-V | Breaking Cybersecurity News | The Hacker News

Microsoft on Tuesday released its monthly security update,  addressing 61 different security flaws  spanning its software, including two critical issues impacting Windows Hyper-V that could lead to denial-of-service (DoS) and remote code execution. Of the 61 vulnerabilities, two are rated Critical, 58 are rated Important, and one is rated Low in severity. None of the flaws are listed as publicly known or under active attack at the time of the release, but six of them have been tagged with an "Exploitation More Likely" assessment. The fixes are in addition to  17 security flaws  that have been patched in the company's Chromium-based Edge browser since the release of the  February 2024 Patch Tuesday updates . Topping the list of critical shortcomings are  CVE-2024-21407  and  CVE-2024-21408 , which affect Hyper-V and could result in remote code execution and a DoS condition, respectively. Microsoft's update also addresses privilege escalation f...

Remember the Reverse RDP Attack ? Earlier this year, researchers disclosed clipboard hijacking and path-traversal issues in Microsoft's Windows built-in RDP client that could allow a malicious RDP server to compromise a client computer, reversely. (You can find details and a video demonstration for this security vulnerability, along with dozens of critical flaws in other third-party RDP clients, in a previous article written by Swati Khandelwal for The Hacker News.) At the time when researchers responsibly reported this path-traversal issue to Microsoft, in October 2018, the company acknowledged the issue, also known as " Poisoned RDP vulnerability ," but decided not to address it. Now, it turns out that Microsoft silently patched this vulnerability  (CVE-2019-0887) just last month as part of its July Patch Tuesday updates after Eyal Itkin, security researcher at CheckPoint, found the same issue affecting Microsoft's Hyper-V technology as well. Microsoft...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

This year, Microsoft impressed the world with 'Microsoft loves Linux' announcements, like developing a custom Linux-based OS for running Azure Cloud Switch, selecting Ubuntu as the operating system for its Cloud-based Big Data services and bringing the popular Bash shell to Windows 10 . Now, the next big news for open-source community: Microsoft has released its own custom distribution of FreeBSD 10.3 as a "ready-made" Virtual Machine image in order to make the operating system available directly from the Azure Marketplace. FreeBSD (Berkeley Software Distribution) is an open source Unix-like advanced computer operating system used to power modern servers, desktops as well as embedded systems. Until now, the only way for Azure customers to run FreeBSD was to make use of a custom image from outside of Azure (from the FreeBSD Foundation). However, the new release makes it easier for Azure users to launch FreeBSD directly from the Azure Marketplace and get...
