Amazon Linux 2 Security Advisory: ALASECS-2022-001
Advisory Release Date: 2022-06-30 00:08 Pacific
Advisory Updated Date: 2023-10-06 23:37 Pacific
2023-10-06: CVE-2022-24769 was added to this advisory.
A bug was found in containerd where containers launched through containerd's CRI implementation with a specially-crafted image configuration could gain access to read-only copies of arbitrary files and directories on the host. This may bypass any policy-based enforcement on container setup (including a Kubernetes Pod Security Policy) and expose potentially sensitive information. Kubernetes and crictl can both be configured to use containerd's CRI implementation. (CVE-2022-23648)
A flaw was found in Moby (Docker Engine), where containers were started incorrectly with non-empty inheritable Linux process capabilities. This flaw allows an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs. Containers using Linux users and groups to perform privilege separation inside the container are most directly impacted. (CVE-2022-24769)
