Debian Security Advisory DSA 425-1 security@debian.org
http://www.debian.org/security/ Matt Zimmerman
January 16th, 2004 http://www.debian.org/security/faq
--------------------------------------------------------------------------

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.
