    It was discovered that nbd-server, the server for the Network Block
    Device protocol, did incorrect parsing of the access control lists,
    allowing access to any hosts with an IP address sharing a prefix with
    an allowed address.
    
    For the oldstable distribution (squeeze), this problem has been fixed in
    version 1:2.9.16-8+squeeze1.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 1:3.2-4~deb7u4.
    
    For the unstable distribution (sid), this problem will be fixed soon.
    
    We recommend that you upgrade your nbd packages.
