Package        : tcpdump
Vulnerability  : multiple vulnerabilities
Problem-Type   : remote
Debian-specific: no
CVE Ids        : CAN-2003-1029 CAN-2003-0989 CAN-2004-0055 CAN-2004-0057

Multiple vulnerabilities were discovered in tcpdump, a tool for
inspecting network traffic.  If a vulnerable version of tcpdump
attempted to examine a maliciously constructed packet, a number of
buffer overflows could be exploited to crash tcpdump, or potentially
execute arbitrary code with the privileges of the tcpdump process.

CAN-2003-1029 - infinite loop and memory consumption in processing
  L2TP packets

CAN-2003-0989, CAN-2004-0057 - infinite loops in processing ISAKMP
  packets.

CAN-2004-0055 - segmentation fault caused by a RADIUS attribute with a
  large length value

For the current stable distribution (woody) these problems have been
fixed in version 3.6.2-2.7.

For the unstable distribution (sid) these problems will be fixed soon.

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.

Debian: tcpdump Multiple vulnerabilities

January 16, 2004
A number of buffer overflows could be exploited to crash tcpdump, or execute arbitrary code with the privileges of tcpdump.

Summary

Multiple vulnerabilities were discovered in tcpdump, a tool for
inspecting network traffic. If a vulnerable version of tcpdump
attempted to examine a maliciously constructed packet, a number of
buffer overflows could be exploited to crash tcpdump, or potentially
execute arbitrary code with the privileges of the tcpdump process.

CAN-2003-1029 - infinite loop and memory consumption in processing
L2TP packets

CAN-2003-0989, CAN-2004-0057 - infinite loops in processing ISAKMP
packets.

CAN-2004-0055 - segmentation fault caused by a RADIUS attribute with a
large length value

For the current stable distribution (woody) these problems have been
fixed in version 3.6.2-2.7.

For the unstable distribution (sid) these problems will be fixed soon.
