    Package        : pdns-recursor
    CVE ID         : CVE-2016-7068
    
    Florian Heinz and Martin Kluge reported that pdns-recursor, a recursive
    DNS server, parses all records present in a query regardless of whether
    they are needed or even legitimate, allowing a remote, unauthenticated
    attacker to cause an abnormal CPU usage load on the pdns server,
    resulting in a partial denial of service if the system becomes
    overloaded.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 3.6.2-2+deb8u3.
    
    We recommend that you upgrade your pdns-recursor packages.
