Detail

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: http://store.mandriva.com/product_info.php?cPath=149&products_id=490

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

Title: DSA-2216-1 isc-dhcp -- missing input sanitisation
Description: Sebastian Krahmer and Marius Tomaschewski discovered that dhclient of isc-dhcp, a DHCP client, is not properly filtering shell meta-characters in certain options in DHCP server responses. These options are reused in an insecure fashion by dhclient scripts. This allows an attacker to execute arbitrary commands with the privileges of such a process by sending crafted DHCP options to a client using a rogue server.
