Beschreibung:	Summary: The remote host is missing an update for the 'dhclient' package(s) announced via the referenced advisory. Vulnerability Insight: 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) An insecure temporary file use flaw was discovered in the DHCP daemon's init script ('/etc/init.d/dhcpd'). A local attacker could use this flaw to overwrite an arbitrary file with the output of the 'dhcpd -t' command via a symbolic link attack, if a system administrator executed the DHCP init script with the 'configtest', &'restart', or 'reload' option. (CVE-2009-1893) Users of DHCP should upgrade to these updated packages, which contain backported patches to correct these issues. Affected Software/OS: dhclient on CentOS 3 Solution: Please install the updated packages. CVSS Score: 10.0 CVSS Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
