Description

The vulnerability allows a remote user to escalate privileges on the system.

The vulnerability exists due to improperly imposed security restrictions during the build process. A remote user can leverage usage of a --mount flag in RUN instructions in Containerfiles along with multi-stage builds with use of concurrently-executing build stages or multiple separate but concurrently-executing builds to expose content from the build host and perform read/write operations on the system with privileges of the podman system service.

Mitigation

Install updates from vendor's website.
