    Domain Name Service server, may overflow an internal buffer when
    handling requests with a large number of labels, causing a server
    crash and the consequent denial of service.
    
    For the oldstable distribution (lenny), this problem has been fixed in
    version 1.3.07.09-2.1.
    
    For the stable distribution (squeeze) and greater this problem had
    already been fixed in version 1.4.03-1.1.
    
    We recommend that you upgrade your maradns packages.
