remote code execution in dhcp-client

Description

The DHCP client (dhclient) could be crashed by a malicious DHCP 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. #### Solution There is no known workaround, please install the update packages.
