CVE-2024-40635
MEDIUM4.6EPSS 0.06%containerd has an integer overflow in User ID handling
Description
### Impact A 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. ### Patches This bug has been fixed in the following containerd versions: * 2.0.4 (Fixed in https://github.com/containerd/containerd/commit/1a43cb6a1035441f9aca8f5666a9b3ef9e70ab20) * 1.7.27 (Fixed in https://github.com/containerd/containerd/commit/05044ec0a9a75232cad458027ca83437aae3f4da) * 1.6.38 (Fixed in https://github.com/containerd/containerd/commit/cf158e884cfe4812a6c371b59e4ea9bc4c46e51a) Users should update to these versions to resolve the issue. ### Workarounds Ensure that only trusted images are used and that only trusted users have permissions to import images. ### Credits The 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). ### References * https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-40635 ### For more information If you have any questions or comments about this advisory: * Open an issue in [containerd](https://github.com/containerd/containerd/issues/new/choose) * Email us at [[email protected]](mailto:[email protected]) To report a security issue in containerd: * [Report a new vulnerability](https://github.com/containerd/containerd/security/advisories/new) * Email us at [[email protected]](mailto:[email protected])
