SCA: security update for github.com/containerd/containerd (GHSA-742w-89gc-8m9c)

medium Tenable Self-Hosted Container Security Plugin ID 433609

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In containerd (an industry-standard container runtime) before version 1.2.14 there is a credential leaking
 vulnerability. If a container image manifest in the OCI Image format or Docker Image V2 Schema 2 format
 includes a URL for the location of a specific image layer (otherwise known as a “foreign layer”), the
 default containerd resolver will follow that URL to attempt to download it. In v1.2.x but not 1.3.0 or
 later, the default containerd resolver will provide its authentication credentials if the server where the
 URL is located presents an HTTP 401 status code along with registry-specific HTTP headers. If an attacker
 publishes a public image with a manifest that directs one of the layers to be fetched from a web server
 they control and they trick a user or system into pulling the image, they can obtain the credentials used
 for pulling that image. In some cases, this may be the user's username and password for the registry. In
 other cases, this may be the credentials attached to the cloud virtual instance which can grant access to
 other cloud resources in the account. The default containerd resolver is used by the cri-containerd plugin
 (which can be used by Kubernetes), the ctr development tool, and other client programs that have
 explicitly linked against it. This vulnerability has been fixed in containerd 1.2.14. containerd 1.3 and
 later are not affected. If you are using containerd 1.3 or later, you are not affected. If you are using
 cri-containerd in the 1.2 series or prior, you should ensure you only pull images from trusted sources.
 Other container runtimes built on top of containerd but not using the default resolver (such as Docker)
 are not affected. (CVE-2020-15157)
