TITLE:
Gentoo update for dhcp

SECUNIA ADVISORY ID:
SA31396

VERIFY ADVISORY:
http://secunia.com/advisories/31396/

CRITICAL:
Not critical

IMPACT:
DoS

WHERE:
>From local network

OPERATING SYSTEM:
Gentoo Linux 1.x
http://secunia.com/product/339/

DESCRIPTION:
Gentoo has issued an update for dhcp. This fixes a weakness, which
can be exploited by malicious people to cause a DoS (Denial of
Service).

The weakness is caused due to an integer overflow error, which can be
exploited to crash the server if a large "dhcp-max-message-size" was
specified by a client.

Note: Successful exploitation requires a server configuration which
provides clients with an unlikely amount of DHCP options.

SOLUTION:
Update to "net-misc/dhcp-3.1.1" or later.
