How to Fix CVE-2022-4123

To remediate this vulnerability, upgrade all affected Github.com/containers/podman/v4 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/v4 fixed: Latest secure release 
Upgrade github.com/containers/podman/v4 to Latest secure release
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/v4

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-4123, inspect your project dependencies for Github.com/containers/podman/v4:

inspect dependencies for github.com/containers/podman/v4

Analyze the terminal output to locate any version of Github.com/containers/podman/v4 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), 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-23: Relative Path Traversal, where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. In Github.com/containers/podman/v4, 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

A flaw was found in Buildah. The local path and the lowest subdirectory may be disclosed due to incorrect absolute path traversal, resulting in an impact to confidentiality.
