  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.");
