Zusammenfassung:	The remote host is missing an update for the 'docker-containerd' package(s) announced via the MGASA-2021-0248 advisory.
Beschreibung:	Summary: The remote host is missing an update for the 'docker-containerd' package(s) announced via the MGASA-2021-0248 advisory. Vulnerability Insight: 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. (CVE-2021-21334). Affected Software/OS: 'docker-containerd' package(s) on Mageia 7, Mageia 8. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:N/A:N
