CVE-2022-23648— containerd 信息泄露漏洞

Insecure handling of image volumes in containerd CRI plugin

containerd is a container runtime available as a daemon for Linux and Windows. A bug was found in containerd prior to versions 1.6.1, 1.5.10, and 1.14.12 where containers launched through containerd’s CRI implementation on Linux 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. This bug has been fixed in containerd 1.6.1, 1.5.10, and 1.4.12. Users should update to these versions to resolve the issue.

信息暴露

containerd 信息泄露漏洞

containerd是美国阿帕奇（Apache）基金会的一个容器守护进程。该进程根据 RunC OCI 规范负责控制宿主机上容器的完整周期。 containerd 1.6.1之前版本, 1.5.10之前版本, 和1.14.12之前版本存在信息泄露漏洞，攻击者可利用该漏洞通过特殊的镜像配置启动容器并访问主机上任意文件和目录的只读副本。这可能绕过任何基于策略的容器设置实施(包括Kubernetes Pod安全策略)，并暴露潜在的敏感信息。
