"A vulnerability has been found and corrected in ISC DHCP :

dhclient in ISC DHCP 3.0.x through 4.2.x before 4.2.1-P1, 3.1-ESV
before 3.1-ESV-R1, and 4.1-ESV before 4.1-ESV-R2 allows remote
attackers to execute arbitrary commands via shell metacharacters in a
hostname obtained from a DHCP message (CVE-2011-0997).

Additionally for Corporate Server 4 and Enterprise Server 5 ISC DHCP
has been upgraded from the 3.0.7 version to the 4.1.2-P1 version which
brings many enhancements such as better ipv6 support.

Packages for 2009.0 are provided as of the Extended Maintenance
Program. Please visit this link to learn more:

The updated packages have upgraded to the 4.1.2-P1 version and patched
to correct this issue."
