tcpdump - multiple vulnerabilities

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.
