Package        : dhcp3
Vulnerability  : several
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2009-0692 CVE-2009-1892
CERT advisory  : VU#410676

The previous dhcp3 update (DSA-1833-1) did not properly apply the
required changes to the stable (lenny) version.  The old stable (etch)
version is not affected by this problem.

The original advisory description follows.

Several remote vulnerabilities have been discovered in ISC's DHCP
implementation:

It was discovered that dhclient does not properly handle overlong
subnet mask options, leading to a stack-based buffer overflow and
possible arbitrary code execution.  (CVE-2009-0692)

Christoph Biedl discovered that the DHCP server may terminate when
receiving certain well-formed DHCP requests, provided that the server
configuration mixes host definitions using "dhcp-client-identifier"
and "hardware ethernet".  This vulnerability only affects the lenny
versions of dhcp3-server and dhcp3-server-ldap.  (CVE-2009-1892)

For the stable distribution (lenny), this problem has been fixed in
version 3.1.1-6+lenny3.

We recommend that you upgrade your dhcp3 packages.

Upgrade instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
