Affected Products and Versions
Severity is high unless otherwise noted.
- All versions of Cloud Foundry BOSH stemcells prior to 3146 are vulnerable.
- All versions of Cloud Foundry cflinuxfs2 prior to v.1.20.0.
Mitigation
Users of affected versions should apply the following mitigation:
- The Cloud Foundry project recommends that Cloud Foundry deployments run with BOSH stemcells 3146 or later versions and cflinuxfs2 v.1.20.0 or later versions.
