    Several vulnerabilities were discovered in Ansible, a configuration
    management, deployment, and task execution system.
    
    CVE-2015-3908
    
        A potential man-in-the-middle attack associated with insusfficient
        X.509 certificate verification.  Ansible did not verify that the
        server hostname matches a domain name in the subject's Common Name
        (CN) or subjectAltName field of the X.509 certificate, which allows
        man-in-the-middle attackers to spoof SSL servers via an arbitrary
        valid certificate.
    
    CVE-2015-6240
    
        A symlink attack that allows local users to escape a restricted
        environment (chroot or jail) via a symlink attack.
    
    CVE-2018-10875
    
        A fix potential arbitrary code execution resulting from reading
        ansible.cfg from a world-writable current working directory.  This
        condition now causes ansible to emit a warning and ignore the
        ansible.cfg in the world-writable current working directory.
    
    CVE-2019-10156
    
        Information disclosure through unexpected variable substitution.
    
    For Debian 8 "Jessie", these problems have been fixed in version
    1.7.2+dfsg-2+deb8u2.
    
    We recommend that you upgrade your ansible packages.
