Summary
Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update
Severity
Important
Notes
Topic: An update for Red Hat Hardened Images RPMs is now available.
Details: This update includes the following RPMs: podman: * podman-5.8.2-1.hum1 (aarch64, x86_64) * podman-docker-5.8.2-1.hum1 (noarch) * podman-machine-5.8.2-1.hum1 (aarch64, x86_64) * podman-remote-5.8.2-1.hum1 (aarch64, x86_64) * podman-tests-5.8.2-1.hum1 (aarch64, x86_64) * podmansh-5.8.2-1.hum1 (aarch64, x86_64) * podman-5.8.2-1.hum1.src (src)

There's a vulnerability in podman where an attacker may use the kube play command to overwrite host files when the kube file container a Secrete or a ConfigMap volume mount and such volume contains a symbolic link to a host file path. In a successful attack, the attacker can only control the target file to be overwritten but not the content to be written into the file. Binary-Affected: podman Upstream-version-introduced: v4.0.0 Upstream-version-fixed: v5.6.1

CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Vendor Fix For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ https://access.redhat.com/errata/RHSA-2026:8211
Workaround Red Hat advises to not run the podman kube play command with untrusted Kubernetes YAML file as input, additionally review the Kubernetes YAML file before running it through podman may help to catch maliciously crafted secretes or volumes that may be used to exploit this vulnerability.

A flaw was found in Podman, a tool for managing containers. This vulnerability, located in the HyperV machine backend, allows for command injection. An attacker who can manipulate the virtual machine (VM) image path can inject and execute arbitrary PowerShell commands. This could lead to unauthorized system-level code execution on Windows installations where Podman is running.

CWE-94 - Improper Control of Generation of Code ('Code Injection')
Vendor Fix For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ https://access.redhat.com/errata/RHSA-2026:8211
