ISC DHCP 4.1.x before 4.1-ESV-R7 and 4.2.x before 4.2.4-P2 allows
remote attackers to cause a denial of service (daemon crash) in
opportunistic circumstances by establishing an IPv6 lease in an
environment where the lease expiration time is later reduced
(CVE-2012-3955).

The updated packages have been patched to correct this issue."
