Scientific Linux Security Update : dhcp on SL3.x, SL4.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

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)
