Garden Nstar vulnerability
Cloud Foundry Foundation
- Garden versions 0.22.0-0.329.0
A vulnerability has been discovered in the garden-linux nstar executable that allows access to files on the host system. By staging an application on Cloud Foundry using Diego and Garden installations with a malicious custom buildpack an end user could read files on the host system that the BOSH-created vcap user has permissions to read and then package them into their app droplet.
Severity is high unless otherwise noted.
- All Garden versions prior to v0.330.0
Users of affected versions should apply the following mitigation:
- The Cloud Foundry project recommends that Cloud Foundry Deployments using Diego and Garden upgrade to Garden Linux Release v0.330.0 or higher. Diego release v0.1444.0 includes Garden Linux v.0.330.0.
