Overview
github.com/kubernetes/kubernetes/pkg/kubelet is a kubelet package.
Affected versions of this package are vulnerable to Symlink Attack due to a symlink race. Every synchronization iteration, the Atomic Writer is looking for files that shouldn't be in a volume, and when it finds it is added to a list. When the search is done it deletes the files in the list. Because the deletion doesn't occur during the finding of the file, a malicious container can set up conditions to change the file selected for deletion with a symlink leading to a different file, which will be deleted.
