    Glen Eustace discovered that the ISC DHCP server, a server for automatic
    IP address assignment, is not properly handling changes in the expiration
    times of a lease.  An attacker may use this flaw to crash the service
    and cause denial of service conditions, by reducing the expiration time
    of an active IPv6 lease.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 4.1.1-P1-15+squeeze8.
