In the CRI stream server, a goroutine is launched to handle terminal resize events if a TTY is requested. If the user's process fails to launch due to, for example, a faulty command, the goroutine will be stuck waiting to send without a receiver, resulting in a memory leak. Kubernetes and crictl can both be configured to use containerd's CRI implementation and the stream server is used for handling container IO.\n\n### Patches\n\nThis bug has been fixed in containerd 1.6.12 and 1.5.16.  Users should update to these versions to resolve the issue.\n\n### Workarounds\n\nEnsure that only trusted images and commands are used and that only trusted users have permissions to execute commands in running containers. \n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* Open an issue in [containerd](https://github.com/containerd/containerd/issues/new/choose)\n* Email us at [security@containerd.io](mailto:security@containerd.io)\n\nTo report a security issue in containerd:\n* [Report a new vulnerability](https://github.com/containerd/containerd/security/advisories/new)\n* Email us at [security@containerd.io](mailto:security@containerd.io)\n\n## Affected packages\n\n- `github.com/containerd/containerd < 1.5.16`\n- `github.com/containerd/containerd >= 1.6.0, < 1.6.12`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `github.com/containerd/containerd 1.5.16`\n- `github.com/containerd/containerd 1.6.12`","depth":"sunlit","depthScore":32,"depthScoreParts":{"impact":31.4,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
