Synopsis:	Critical: dhcp security update
Issue date:	2009-07-14
CVE Names:	CVE-2009-0692 CVE-2009-1893

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.
