    Package        : puppet
    CVE ID         : CVE-2017-2295
    
    It was discovered that unrestricted YAML deserialisation of data sent
    from agents to the server in the Puppet configuration management system
    could result in the execution of arbitrary code.
    
    Note that this fix breaks backward compability with Puppet agents older
    than 3.2.2 and there is no safe way to restore it. This affects puppet
    agents running on Debian wheezy; we recommend to update the the
    puppet version shipped in wheezy-backports.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 3.7.2-4+deb8u1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 4.8.2-5.
    
    We recommend that you upgrade your puppet packages.
