Description
containerd is an open-source container runtime. Versions 1.7.28 and below, 2.0.0-beta.0 through 2.0.6, 2.1.0-beta.0 through 2.1.4, and 2.2.0-beta.0 through 2.2.0-rc.1 contain a bug in the CRI Attach implementation where a user can exhaust memory on the host due to goroutine leaks. This issue is fixed in versions 1.7.29, 2.0.7, 2.1.5 and 2.2.0. To workaround this vulnerability, users can set up an admission controller to control accesses to pods/attach resources.

Executive Summary

This vulnerability is a bug in the containerd container runtime's CRI Attach implementation that causes a memory leak on the host system. Specifically, it involves goroutine leaks that allow a user to exhaust the host's memory, potentially leading to denial of service or degraded performance. The issue affects certain versions of containerd and is fixed in later versions.

Impact Analysis

The vulnerability can impact you by allowing a user to exhaust the host system's memory due to goroutine leaks in containerd. This can lead to system instability, degraded performance, or denial of service conditions on the host running containerd.

Mitigation Strategies

To mitigate this vulnerability, users can set up an admission controller to control accesses to pods/attach resources. Additionally, upgrading containerd to a fixed version such as 1.7.29, 2.0.7, 2.1.5, or 2.2.0 is recommended.
