Amazon Linux 2 : amazon-efs-utils (ALAS-2023-2342)

medium Nessus Plugin ID 185788

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of amazon-efs-utils installed on the remote host is prior to 1.35.0-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2342 advisory.

- efs-utils is a set of Utilities for Amazon Elastic File System (EFS). A potential race condition issue exists within the Amazon EFS mount helper in efs-utils versions v1.34.3 and below. When using TLS to mount file systems, the mount helper allocates a local port for stunnel to receive NFS connections prior to applying the TLS tunnel. In affected versions, concurrent mount operations can allocate the same local port, leading to either failed mount operations or an inappropriate mapping from an EFS customer's local mount points to that customer's EFS file systems. This issue is patched in version v1.34.4. There is no recommended work around. We recommend affected users update the installed version of efs-utils to v1.34.4 or later. (CVE-2022-46174)

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 amazon-efs-utils' to update your system.
