RedHat Security Advisory RHSA-2009:1136

Summary
The remote host is missing updates announced in advisory RHSA-2009:1136. 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. The Mandriva Linux Engineering Team discovered a stack-based buffer overflow flaw in the ISC DHCP client. If the DHCP client were to receive a malicious DHCP response, it could crash or execute arbitrary code with the permissions of the client (root). (CVE-2009-0692) Users of DHCP should upgrade to these updated packages, which contain a backported patch to correct this issue.
