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

The patch used to correct the DHCP server buffer overflow in DSA-1388-1
was incomplete and did not adequately resolve the problem.  This update
to the previous advisory makes available updated packages based on a
newer version of the patch.

For the stable distribution (etch), this problem has been fixed in
version 2.0pl5-19.5etch2

Updates to the old stable version (sarge) are pending.

We recommend that you upgrade your dhcp 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.

Debian (stable)
- ---------------

Stable updates are available for alpha, amd64, arm, hppa, i386, ia64, mips, mipsel, powerpc, s390 and sparc.
