		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">containerd security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for containerd is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP3 and openEuler-22.03-LTS.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">containerd is an industry-standard container runtime with an emphasis on simplicity, robustness and portability.  It is available as a daemon for Linux and Windows, which can manage the complete container lifecycle of its host system: image transfer and storage, container execution and supervision, low-level storage and network attachments, etc.

Security Fix(es):

containerd is an open source container runtime. A bug was found in the containerd&apos;s CRI implementation where programs inside a container can cause the containerd daemon to consume memory without bound during invocation of the `ExecSync` API. This can cause containerd to consume all available memory on the computer, denying service to other legitimate workloads. Kubernetes and crictl can both be configured to use containerd&apos;s CRI implementation; `ExecSync` may be used when running probes or when executing processes via an &quot;exec&quot; facility. This bug has been fixed in containerd 1.6.6 and 1.5.13. Users should update to these versions to resolve the issue. Users unable to upgrade should ensure that only trusted images and commands are used.(CVE-2022-31030)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for containerd is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP3 and openEuler-22.03-LTS.

openEuler Security has rated this update as having a security impact of medium. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
