and 1.4.4, containers launched through containerd's CRI implementation
(through Kubernetes, crictl, or any other pod/container client that uses the
containerd CRI service) that share the same image may receive incorrect
environment variables, including values that are defined for other
containers. If the affected containers have different security contexts, this
may allow sensitive information to be unintentionally shared. If you are not
using containerd's CRI implementation (through one of the mechanisms
described above), you are not vulnerable to this issue. If you are not
launching multiple containers or Kubernetes pods from the same image which
have different environment variables, you are not vulnerable to this issue.
If you are not launching multiple containers or Kubernetes pods from the same
image in rapid succession, you have reduced likelihood of being vulnerable to
this issue This vulnerability has been fixed in containerd 1.3.10 and
containerd 1.4.4. (CVE-2021-21334).");
