    Package        : supervisor
    CVE ID         : CVE-2017-11610
    Debian Bug     : 870187
    
    Calum Hutton reported that the XML-RPC server in supervisor, a system
    for controlling process state, does not perform validation on requested
    XML-RPC methods, allowing an authenticated client to send a malicious
    XML-RPC request to supervisord that will run arbitrary shell commands on
    the server as the same user as supervisord.
    
    The vulnerability has been fixed by disabling nested namespace lookup
    entirely. supervisord will now only call methods on the object
    registered to handle XML-RPC requests and not any child objects it may
    contain, possibly breaking existing setups. No publicly available
    plugins are currently known that use nested namespaces. Plugins that use
    a single namespace will continue to work as before. Details can be found
    on the upstream issue at
    https://github.com/Supervisor/supervisor/issues/964 .
    
    For the oldstable distribution (jessie), this problem has been fixed
    in version 3.0r1-1+deb8u1.
    
    For the stable distribution (stretch), this problem has been fixed in
    version 3.3.1-1+deb9u1.
    
    We recommend that you upgrade your supervisor packages.
