In containerd (an industry-standard container runtime) before versions
1.3.10 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. Users should update to
these versions.
