server sending an overlong subnet field (CVE-2009-0692).

In theory a malicious DHCP server could exploit the flaw to execute
arbitrary code as root on machines using dhclient to obtain network
settings. Newer distributions (SLES10+, openSUSE) do have buffer
overflow checking that guards against this kind of stack overflow
though. So actual exploitability is rather unlikely.");
