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

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 Popławski 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 Cont...
Unpatched VirtualBox Zero-Day Vulnerability and Exploit Released Online

Unpatched VirtualBox Zero-Day Vulnerability and Exploit Released Online

Nov 08, 2018
An independent exploit developer and vulnerability researcher has publicly disclosed a zero-day vulnerability in VirtualBox —a popular open source virtualization software developed by Oracle—that could allow a malicious program to escape virtual machine (guest OS) and execute code on the operating system of the host machine. The vulnerability occurs due to memory corruption issues and affects Intel PRO / 1000 MT Desktop (82540EM) network card (E1000) when the network mode is set to NAT (Network Address Translation). The flaw is independent of the type of operating system being used by the virtual and host machines because it resides in a shared code base. VirtualBox Zero-Day Exploit and Demo Video Released Sergey Zelenyuk published Wednesday a detailed technical explanation of the zero-day flaw on GitHub, which affects all current versions (5.2.20 and prior) of VirtualBox software and is present on the default Virtual Machine (VM) configuration. According to Zelenyuk, t...
The Identities Behind AI Agents: A Deep Dive Into AI and NHI

The Identities Behind AI Agents: A Deep Dive Into AI and NHI

Apr 10, 2025AI Security / Enterprise Security
AI agents have rapidly evolved from experimental technology to essential business tools. The OWASP framework explicitly recognizes that Non-Human Identities play a key role in agentic AI security. Their analysis highlights how these autonomous software entities can make decisions, chain complex actions together, and operate continuously without human intervention. They're no longer just tools, but an integral and significant part of your organization's workforce. Consider this reality: Today's AI agents can analyze customer data, generate reports, manage system resources, and even deploy code, all without a human clicking a single button. This shift represents both tremendous opportunity and unprecedented risk. AI Agents are only as secure as their NHIs Here's what security leaders are not necessarily considering: AI agents don't operate in isolation . To function, they need access to data, systems, and resources. This highly privileged, often overlooked acces...
Foreshadow Attacks — 3 New Intel CPU Side-Channel Flaws Discovered

Foreshadow Attacks — 3 New Intel CPU Side-Channel Flaws Discovered

Aug 15, 2018
2018 has been quite a tough year for Intel. While the chip-maker giant is still dealing with Meltdown and Spectre processor vulnerabilities, yet another major speculative execution flaw has been revealed in Intel's Core and Xeon lines of processors that may leave users vulnerable to cyber-attacks. Dubbed Foreshadow , alternatively called L1 Terminal Fault or L1TF, the new attacks include three new speculative execution side-channel vulnerabilities affecting Intel processors. The Foreshadow attacks could allow a hacker or malicious application to gain access to the sensitive data stored in a computer's memory or third-party clouds, including files, encryption keys, pictures, or passwords. The three Foreshadow vulnerabilities have been categorized into two variants: 1.) Foreshadow Foreshadow ( PDF ) targets a new technology originally been designed to protect select code and users' data from disclosure or modification, even if the entire system falls under a...
