tid-207
Vulnerability from emb3d
Type
Description
Container environments, such as Docker and Kubernetes, share the same underlying kernel as the host operating system. Malicious code that succeeds in executing within a container may attempt to exploit any vulnerabilities present in exposed OS system calls, container management system functions, excessive permissions in shared resources, or other misconfigurations in the environment. One or more of these can be sufficient for a threat actor to escape the container into the underlying host and then begin manipulating the host OS or the applications and data within other containers resident on the device.

Summary
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.

- CWE-190 - Integer Overflow or Wraparound
Summary
A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system.
