Rocky Linux 8 : container-tools:2.0 (RLSA-2021:0706)

high Nessus Plugin ID 184724

Synopsis

The remote Rocky Linux host is missing a security update.

Description

The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2021:0706 advisory.

- A flaw was found in podman before 1.7.0. File permissions for non-root users running in a privileged container are not correctly checked. This flaw can be abused by a low-privileged user inside the container to access any other file in the container, even if owned by the root user inside the container. It does not allow to directly escape the container, though being a privileged container means that a lot of security features are disabled when running the container. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2021-20188)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
