How to Fix CVE-2020-14370

To remediate this vulnerability, upgrade all affected Github.com/containers/podman/v2 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/containers/podman/v2 fixed: 2.0.5 
Upgrade github.com/containers/podman/v2 to 2.0.5
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/containers/podman/v2

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-14370, inspect your project dependencies for Github.com/containers/podman/v2:

inspect dependencies for github.com/containers/podman/v2

Analyze the terminal output to locate any version of Github.com/containers/podman/v2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.5), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer, where the product stores, transfers, or shares a resource that contains sensitive information, but it does not properly remove that information before the product makes the resource available to unauthorized actors. In Github.com/containers/podman/v2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

An information disclosure vulnerability was found in containers/podman in versions before 2.0.5. When using the deprecated Varlink API or the Docker-compatible REST API, if multiple containers are created in a short duration, the environment variables from the first container will get leaked into subsequent containers. An attacker who has control over the subsequent containers could use this flaw to gain access to sensitive information stored in such variables.
