Package        : dhcp
Vulnerability  : buffer overflow
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2007-5365
Debian Bug     : 446354

It was discovered that dhcp, a DHCP server for automatic IP address assignment,
didn't correctly allocate space for network replies.  This could potentially
allow a malicious DHCP client to execute arbitary code upon the DHCP server.

For the old stable distribution (sarge), this problem has been fixed in
version 2.0pl5-19.1sarge3.

For the stable distribution (etch), this problem has been fixed in
version 2.0pl5-19.5etch1.

For the unstable distribution (sid), this problem will be fixed shortly.

We recommend that you upgrade your dhcp package.


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.
