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

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

February 12, 2019Mohit Kumar
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 Containe
Android P to Block Apps From Monitoring Device Network Activity

Android P to Block Apps From Monitoring Device Network Activity

May 07, 2018Swati Khandelwal
Do you know that any app you have installed on your Android phone can monitor the network activities—even without asking for any sensitive permission—to detect when other apps on your phone are connecting to the Internet? Obviously, they cant see the content of the network traffic, but can easily find to which server you are connecting to, all without your knowledge. Knowing what apps you often use, which could be a competing or a financial app, "shady" or "malicious" app can abuse this information in various ways to breach your privacy. But it seems like Google has planned to address this serious privacy issue with the release of its next flagship mobile operating system. With Android P, any app will no longer be able to detect when other apps on your Android device are connecting to the Internet, according to the new code changes in Android Open Source Project (AOSP) first noticed by XDA Developers. "A new commit has appeared in the Android Open S

NSA Opens Github Account — Lists 32 Projects Developed by the Agency

The National Security Agency (NSA) — the United States intelligence agency which is known for its secrecy and working in the dark — has finally joined GitHub and launched an official GitHub page. The NSA employs genius-level coders and brightest mathematicians, who continually work to break codes, gather intelligence on everyone, and develop hacking tools like EternalBlu e that was leaked by the Shadow Brokers in April and abused by the WannaCry ransomware last month to wreak havoc worldwide. The intelligence agency mostly works in secret, but after Edward Snowden leaks in 2013, the NSA has started (slowly) opening itself to the world. It joined Twitter in the same year after Snowden leaks and now opened a Github account. GitHub is an online service designed for sharing code amongst programmers and open source community, and so far, the NSA is sharing 32 different projects as part of the NSA Technology Transfer Program ( TTP ), while some of these are 'coming soon.'
