Amazon Linux 2 : containerd (ALASECS-2023-030)

medium Nessus Plugin ID 185923

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 1.4.1-2. It is, therefore, affected by a vulnerability as referenced in the ALAS2ECS-2023-030 advisory.

A flaw was found in containerd. Access controls for the shim API socket verified that a connecting process had an effective UID of 0, but otherwise did not restrict access to the abstract Unix domain socket. This could allow malicious containers running in the same network namespace as the shim, with an effective UID of 0 but otherwise reduced privileges, to cause new processes to be run with elevated privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-15257)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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.
