Amazon Linux AMI : containerd (ALAS-2021-1523)

medium Nessus Plugin ID 151933

Language:

Synopsis

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

Description

The version of containerd installed on the remote host is prior to 1.4.6-2.7. It is, therefore, affected by a vulnerability as referenced in the ALAS-2021-1523 advisory.

 A bug was discovered in containerd where pulling and extracting a specially-crafted container image can result in Unix file permission changes for existing files in the host's filesystem. Changes to file permissions can deny access to the expected owner of the file or widen access to others. (CVE-2021-32760)

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.
