Trustix Secure Linux Bugfix Advisory #2003-0012

Package name:      tcpdump
Summary:           Minor bugfix
Date:              2003-03-18
Affected versions: TSL 1.1, 1.2, 1.5

- --------------------------------------------------------------------------
Package description:
  Tcpdump is a command-line tool for monitoring network traffic.
  Tcpdump can capture and display the packet headers on a particular
  network interface or on all interfaces.  Tcpdump can display all of
  the packet headers, or just the ones that match particular criteria.


Problem description:
  By sending a special network package, an attacker could cause tcpdump
  to enter an infinite loop and thus blinding an intrusion detection
  system or preventing a admin from seeing what happens on the network.

  In addition to tcpdump, the libpcap package has been upgrade to match
  as well.


Action:
  We recommend that all systems with this package installed be upgraded.
  Please note that if you do not need the functionality provided by this
  package, you may want to remove it from your system.
