Attacking Containers and runC
This week a new vulnerability was published CVE-2019-5736 that highlights everything bad and good about containers. Simply put, this vulnerability can be exploited using an infected container to attack the host. It’s a real world example of a breakout attack that has long been a major concern in...
RunC Container Breakout Vulnerability
Despite the huge advantages that containers offer in application portability, acceleration of CI/CD pipelines and agility of deployment environments, the biggest concern has always been about isolation. Since all the containers running on a host share the same underlying kernel, any malicious cod...
RunC Flaw Lets Attackers Escape Linux Containers to Gain Root on Hosts
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,...
