    Package        : coturn
    CVE ID         : CVE-2018-4056 CVE-2018-4058 CVE-2018-4059
    
    Multiple vulnerabilities were discovered in coTURN, a TURN and STUN server for
    VoIP.
    
    CVE-2018-4056
    
        An SQL injection vulnerability was discovered in the coTURN administrator
        web portal. As the administration web interface is shared with the
        production, it is unfortunately not possible to easily filter outside
        access and this security update completely disable the web interface. Users
        should use the local, command line interface instead.
    
    CVE-2018-4058
    
        Default configuration enables unsafe loopback forwarding. A remote attacker
        with access to the TURN interface can use this vulnerability to gain access
        to services that should be local only.
    
    CVE-2018-4059
    
        Default configuration uses an empty password for the local command line
        administration interface. An attacker with access to the local console
        (either a local attacker or a remote attacker taking advantage of
        CVE-2018-4058) could escalade privileges to administrator of the coTURN
        server.
    
    For the stable distribution (stretch), these problems have been fixed in
    version 4.5.0.5-1+deb9u1.
    
    We recommend that you upgrade your coturn packages.
