Description:
Previous versions of the ISC DHCP server were vulnerable to denial
of service or arbitrary code execution attacks via malformed DHCP
packets with a large dhcp-max-message-size that trigger a
stack-based buffer overflow.

Note that rPath Linux 2 is susceptible only to a Denial of Service
in this case, due to the stack protector feature enabled as part of
rPath Linux 2.
