Synopsis: Important: dhcp security update
Issue date: 2011-04-08
CVE Names: CVE-2011-0997

It was discovered that the DHCP client daemon, dhclient, did not
sufficiently sanitize certain options provided in DHCP server replies, such
as the client hostname. A malicious DHCP server could send such an option
with a specially-crafted value to a DHCP client. If this option's value was
saved on the client system, and then later insecurely evaluated by a
process that assumes the option is trusted, it could lead to arbitrary code
execution with the privileges of that process. (CVE-2011-0997)
