SCA: security update for github.com/containers/storage (GHSA-7qw8-847f-pggm)

medium Tenable Cloud Security Plugin ID 412216

Description

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

 - A deadlock vulnerability was found in 'github.com/containers/storage' in versions before 1.28.1. When a
 container image is processed, each layer is unpacked using `tar`. If one of those layers is not a valid
 `tar` archive this causes an error leading to an unexpected situation where the code indefinitely waits
 for the tar unpacked stream, which never finishes. An attacker could use this vulnerability to craft a
 malicious image, which when downloaded and stored by an application using containers/storage, would then
 cause a deadlock leading to a Denial of Service (DoS). (CVE-2021-20291)
