How to Fix CVE-2024-40635

To remediate this vulnerability, upgrade all affected Github.com/containerd/containerd/v2 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/containerd/containerd/v2 fixed: 2.0.4
Upgrade github.com/containerd/containerd/v2 to 2.0.4
github.com/containerd/containerd fixed: 1.7.27
Upgrade github.com/containerd/containerd to 1.7.27
github.com/containerd/containerd fixed: 1.6.38
Upgrade github.com/containerd/containerd to 1.6.38
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for github.com/containerd/containerd/v2

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-40635, inspect your project dependencies for Github.com/containerd/containerd/v2:

inspect dependencies for github.com/containerd/containerd/v2

Analyze the terminal output to locate any version of Github.com/containerd/containerd/v2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.4), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-190: Integer Overflow or Wraparound, where the product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. this occurs when an integer value is incremented to a value that is too large to store in the associated representation. when this occurs, the value may become a very small or negative number. In Github.com/containerd/containerd/v2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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 [security@containerd.io](mailto:security@containerd.io) To report a security issue in containerd: * [Report a new vulnerability](https://github.com/containerd/containerd/security/advisories/new) * Email us at [security@containerd.io](mailto:security@containerd.io)
