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)","affected":[{"package":{"name":"github.com/containerd/containerd","ecosystem":"Go","purl":"pkg:golang/github.com/containerd/containerd"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.5.16"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/12/GHSA-2qjp-425j-52j9/GHSA-2qjp-425j-52j9.json"}},{"package":{"name":"github.com/containerd/containerd","ecosystem":"Go","purl":"pkg:golang/github.com/containerd/containerd"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.6.0"},{"fixed":"1.6.12"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/12/GHSA-2qjp-425j-52j9/GHSA-2qjp-425j-52j9.json"}}],"references":[{"type":"WEB","url":"https://github.com/containerd/containerd/security/advisories/GHSA-2qjp-425j-52j9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23471"},{"type":"WEB","url":"https://github.com/containerd/containerd/commit/241563be06a3de8b6a849414c4e805b68d3bb295"},{"type":"WEB","url":"https://github.com/containerd/containerd/commit/a05d175400b1145e5e6a735a6710579d181e7fb0"},{"type":"PACKAGE","url":"https://github.com/containerd/containerd"},{"type":"WEB","url":"https://github.com/containerd/containerd/releases/tag/v1.5.16"},{"type":"WEB","url":"https://github.com/containerd/containerd/releases/tag/v1.6.12"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202401-31"}],"database_specific":{"cwe_ids":["CWE-400","CWE-401"],"github_reviewed":true,"github_reviewed_at":"2022-12-07T23:23:43Z","nvd_published_at":"2022-12-07T23:15:00Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H"}]}
