A flaw was found in Ansible. The ansible-core user module can allow an unprivileged user to silently create or replace the contents of any file on any system path and take ownership of it when a privileged user executes the user module against the unprivileged user's home directory. If the unprivileged user has traversal permissions on the directory containing the exploited target file, they retain full control over the contents of the file as its owner.

A flaw was found in ansible-core. The ansible-galaxy role install command processes dependency specifications from a role's meta/requirements.yml file. Due to improper neutralization of argument delimiters, a malicious role author can inject arbitrary git configuration flags through the src field. This allows arbitrary code execution on the machine of a user who installs the role via ansible-galaxy role install.

Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments.This advisory contains the RPM packages for Red Hat OpenShift Container Platform 4.21.39.

To check for available updates, use the OpenShift CLI (oc) or web console. Instructions for upgrading a cluster are available at https://docs.redhat.com/en/documentation/openshiftcontainerplatform/4.21/html-single/updatingclusters/index#updating-cluster-cli.

A flaw was found in ansible-core's ansible-galaxy command. When installing a role, ansible-galaxy processes a meta/requirements.yml file that lists role dependencies. The src and name fields from this file are passed as arguments to git clone via Python's Popen without a -- separator to delimit options from positional arguments. A malicious role author can craft a dependency entry where the src field contains a git configuration flag (e.g., -ccore.sshCommand=sh -c "maliciouscommand") and the name field provides a valid repository URL. This results in arbitrary code execution on the system of any user who installs the role. The fix is to insert -- before the positional arguments in the git clone command list.
