    Several denial-of-service vulnerabilities (assertion failures) were
    discovered in BIND, a DNS server implementation.
    
    CVE-2016-9131
    
        A crafted upstream response to an ANY query could cause an
        assertion failure.
    
    CVE-2016-9147
    
        A crafted upstream response with self-contradicting DNSSEC data
        could cause an assertion failure.
    
    CVE-2016-9444
    
        Specially-crafted upstream responses with a DS record could cause
        an assertion failure.
    
    These vulnerabilities predominantly affect DNS servers providing
    recursive service.  Client queries to authoritative-only servers
    cannot trigger these assertion failures.  These vulnerabilities are
    present whether or not DNSSEC validation is enabled in the server
    configuration.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 1:9.9.5.dfsg-9+deb8u9.
    
    We recommend that you upgrade your bind9 packages.
