Package        : tcpdump
Vulnerability  : denial of service
Problem-Type   : remote
Debian-specific: no
CVE Ids        : CAN-2004-0183 CAN-2004-0184

tcpdump, a tool for network monitoring and data acquisition, was found
to contain two vulnerabilities whereby tcpdump could be caused to
crash through attempts to read from invalid memory locations.  This
bug is triggered by certain invalid ISAKMP packets.

For the current stable distribution (woody) these problems have been
fixed in version 3.6.2-2.8.

For the unstable distribution (sid), these problems have been fixed in
version 3.7.2-4.

We recommend that you update your tcpdump 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.
