TITLE:
rPath update for dhclient, dhcp, and  libdhcp4client

SECUNIA ADVISORY ID:
SA34263

VERIFY ADVISORY:
http://secunia.com/advisories/34263/

DESCRIPTION:
rPath has issued an update for dhclient, dhcp, and libdhcp4client.
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:
dhclient=conary.rpath.com@rpl:1/3.0.7-0.4-1
dhclient=conary.rpath.com@rpl:2/3.1.2-0.2-1
dhcp=conary.rpath.com@rpl:1/3.0.7-0.4-1
dhcp=conary.rpath.com@rpl:2/3.1.2-0.2-1
libdhcp4client=conary.rpath.com@rpl:2/3.1.2-0.2-1
