{"id":"GHSA-265r-hfxg-fhmg","summary":"containerd has an integer overflow in User ID handling","details":"### Impact\nA bug was found in containerd where containers launched with a User set as a `UID:GID` larger than the maximum 32-bit signed integer can cause an overflow condition where the container ultimately runs as root (UID 0). This could cause unexpected behavior for environments that require containers to run as a non-root user.\n\n### Patches\nThis bug has been fixed in the following containerd versions: \n\n* 2.0.4 (Fixed in https://github.com/containerd/containerd/commit/1a43cb6a1035441f9aca8f5666a9b3ef9e70ab20)\n* 1.7.27 (Fixed in https://github.com/containerd/containerd/commit/05044ec0a9a75232cad458027ca83437aae3f4da)\n* 1.6.38 (Fixed in https://github.com/containerd/containerd/commit/cf158e884cfe4812a6c371b59e4ea9bc4c46e51a)\n\nUsers should update to these versions to resolve the issue.\n\n### Workarounds\nEnsure that only trusted images are used and that only trusted users have permissions to import images.\n\n### Credits\nThe containerd project would like to thank [Benjamin Koltermann](https://github.com/p4ck3t0) and [emxll](https://github.com/emxll) for responsibly disclosing this issue in accordance with the [containerd security policy](https://github.com/containerd/project/blob/main/SECURITY.md).\n\n### References\n* https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-40635\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)","aliases":["CVE-2024-40635","GO-2025-3528"],"modified":"2026-02-04T03:46:34.655580Z","published":"2025-03-17T21:24:42Z","related":["CGA-2ffc-vqv2-m9xj"],"database_specific":{"cwe_ids":["CWE-190"],"github_reviewed_at":"2025-03-17T21:24:42Z","github_reviewed":true,"nvd_published_at":"2025-03-17T22:15:13Z","severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/containerd/containerd/security/advisories/GHSA-265r-hfxg-fhmg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-40635"},{"type":"WEB","url":"https://github.com/containerd/containerd/commit/05044ec0a9a75232cad458027ca83437aae3f4da"},{"type":"WEB","url":"https://github.com/containerd/containerd/commit/1a43cb6a1035441f9aca8f5666a9b3ef9e70ab20"},{"type":"WEB","url":"https://github.com/containerd/containerd/commit/cf158e884cfe4812a6c371b59e4ea9bc4c46e51a"},{"type":"PACKAGE","url":"https://github.com/containerd/containerd"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00005.html"}],"affected":[{"package":{"name":"github.com/containerd/containerd/v2","ecosystem":"Go","purl":"pkg:golang/github.com/containerd/containerd/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.0.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-265r-hfxg-fhmg/GHSA-265r-hfxg-fhmg.json"}},{"package":{"name":"github.com/containerd/containerd","ecosystem":"Go","purl":"pkg:golang/github.com/containerd/containerd"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.7.0-beta.0"},{"fixed":"1.7.27"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-265r-hfxg-fhmg/GHSA-265r-hfxg-fhmg.json"}},{"package":{"name":"github.com/containerd/containerd","ecosystem":"Go","purl":"pkg:golang/github.com/containerd/containerd"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.6.38"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-265r-hfxg-fhmg/GHSA-265r-hfxg-fhmg.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N"}]}
