Amazon Linux 2 : containerd (ALASECS-2023-026)

medium Nessus Plugin ID 185919

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of containerd installed on the remote host is prior to 1.4.6-7. It is, therefore, affected by a vulnerability as referenced in the ALAS2ECS-2023-026 advisory.

- The OCI Distribution Spec project defines an API protocol to facilitate and standardize the distribution of content. In the OCI Distribution Specification version 1.0.0 and prior, the Content-Type header alone was used to determine the type of document during push and pull operations. Documents that contain both manifests and layers fields could be interpreted as either a manifest or an index in the absence of an accompanying Content-Type header. If a Content-Type header changed between two pulls of the same digest, a client may interpret the resulting content differently. The OCI Distribution Specification has been updated to require that a mediaType value present in a manifest or index match the Content-Type header used during the push and pull operations. Clients pulling from a registry may distrust the Content-Type header and reject an ambiguous document that contains both manifests and layers fields or manifests and config fields if they are unable to update to version 1.0.1 of the spec. (CVE-2021-41190)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update containerd' to update your system.
