3. Description:

The Dynamic Host Configuration Protocol (DHCP) is a protocol that allows
individual devices on an IP network to get their own network configuration
information, including an IP address, a subnet mask, and a broadcast
address.

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)

Red Hat would like to thank Sebastian Krahmer of the SuSE Security Team for
reporting this issue.

All dhclient users should upgrade to these updated packages, which contain
a backported patch to correct this issue.
