    Package        : bind9
    CVE ID         : CVE-2015-8000
    Debian Bug     : 808081
    
    It was discovered that the BIND DNS server does not properly handle the
    parsing of incoming responses, allowing some records with an incorrect
    class to be accepted by BIND instead of being rejected as malformed.
    This can trigger a REQUIRE assertion failure when those records are
    subsequently cached. A remote attacker can exploit this flaw to cause a
    denial of service against servers performing recursive queries.
    
    For the oldstable distribution (wheezy), this problem has been fixed
    in version 1:9.8.4.dfsg.P1-6+nmu2+deb7u8.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 1:9.9.5.dfsg-9+deb8u4.
    
    We recommend that you upgrade your bind9 packages.
