CVE-2019-5736 - Vulncode-DB

CVE-2019-5736 (NVD)

2019-02-11

runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe.

Products	Mesos, Ubuntu_linux, Dc\/os, Kubernetes_engine, Docker, Fedora, Kubernetes_engine, Onesphere, Lxc, Runc, Service_management_automation, Hci_management_node, Solidfire, Backports_sle, Leap, Container_development_kit, Enterprise_linux, Enterprise_linux_server, Openshift
Type	Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') (CWE-78)
