CVE-2012-3571 Markus Hietava of the Codenomicon CROSS project discovered that it is possible to force the server to enter an infinite loop via messages with malformed client identifiers. CVE-2012-3954 Glen Eustace discovered that DHCP servers running in DHCPv6 mode and possibly DHCPv4 mode suffer of memory leaks while processing messages. An attacker can use this flaw to exhaust resources and perform denial of service attacks. For the stable distribution (squeeze), this problem has been fixed in version 4.1.1-P1-15+squeeze4. For the testing (wheezy) and unstable (sid) distributions, this problem will be fixed soon. We recommend that you upgrade your isc-dhcp packages.
