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)
Run yum update containerd to update your system.
