    CVE ID         : CVE-2014-8602
    Debian Bug     : 772622
    
    Florian Maury from ANSSI discovered that unbound, a validating,
    recursive, and caching DNS resolver, was prone to a denial of service
    vulnerability. An attacker crafting a malicious zone and able to emit
    (or make emit) queries to the server can trick the resolver into
    following an endless series of delegations, leading to ressource
    exhaustion and huge network usage.
    
    For the stable distribution (wheezy), this problem has been fixed in
