RunC Flaw Lets Attackers Escape Linux Containers to Gain Root on Hosts

Feb 12, 2019
A serious security vulnerability has been discovered in the core runC container code that affects several open-source container management systems, potentially allowing attackers to escape Linux container and obtain unauthorized, root-level access to the host operating system. The vulnerability, identified as  CVE-2019-5736 , was discovered by open source security researchers Adam Iwaniuk and Borys PopÅ‚awski and publicly disclosed by Aleksa Sarai, a senior software engineer and runC maintainer at SUSE Linux GmbH on Monday. The flaw resides in runC—a lightweight low-level command-line tool for spawning and running containers, an operating-system-level virtualization method for running multiple isolated systems on a host using a single kernel. Originally created by Docker, runC is the default container run-time for Docker, Kubernetes, ContainerD, CRI-O, and other container-dependent programs, and is widely being used by major cloud hosting and server providers. runC Containe

SUSE Linux Has Been Sold For $2.5 Billion

Jul 03, 2018
SUSE, the open source software company owned by British firm Micro Focus International, has been sold to a Swedish private equity firm. Yes, SUSE Linux and its associated software business has finally been acquired by EQT Partners for $2.535 billion, lifting its shares 6 percent. SUSE is one of the oldest open source companies and perhaps the first to provide enterprise-grade Linux software service to banks, universities and government agencies around the world. Since its foundation in 1992, SUSE has changed ownership multiple times. US-based software company Novell acquired SUSE for $120 million in November 2003 to compete with Microsoft in the operating system market. However, things did not work as the company thought and Novell in turn itself was acquired by another US-based company The Attachmate Group for $2.2 billion in 2011. Three years later, Micro Focus International acquired Attachmate for $2.35 billion in 2014. Since then SUSE Linux has been part of Micro Focus
How to Increase Engagement with Your Cybersecurity Clients Through vCISO Reporting

How to Increase Engagement with Your Cybersecurity Clients Through vCISO Reporting

Jul 22, 2024vCISO / Business Security
As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.
