    Debian Bug     : 1082851

    Ansible is a command-line IT automation software application.
    It can configure systems, deploy software, and orchestrate
    advanced workflows to support application deployment, system updates, ...

    Ansible was affected by two vulnerabilities:

    CVE-2024-8775

        A flaw was found in Ansible, where sensitive information stored in
        Ansible Vault files can be exposed in plaintext during the execution
        of a playbook. This occurs when using tasks such as include_vars to
        load vaulted variables without setting the no_log: true parameter,
        resulting in sensitive data being printed in the playbook output or
        logs. This can lead to the unintentional disclosure of secrets like
        passwords or API keys, compromising security and potentially
        allowing unauthorized access or actions.

    CVE-2024-9902

        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.

    For Debian 11 bullseye, these problems have been fixed in version
    2.10.7+merged+base+2.10.17+dfsg-0+deb11u2.

    We recommend that you upgrade your ansible packages.

    its security tracker page at:
