Tcpdump critical alert related to denial of service risk; update recommended for Debian users to ensure system security.
Crafted invalid ISAKMP packets can remotely crash tcpdump.

Summary

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.
