Synopsis
========

A heap-based buffer overflow in TCPTrack might allow a remote attacker
to execute arbitrary code.

Background
==========

TCPTrack is a simple libpcap based program for live TCP connection
monitoring.

Affected packages
=================

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 net-analyzer/tcptrack < 1.4.2 >= 1.4.2

Description
===========

A heap-based buffer overflow vulnerability exists in TCPTrack’s parsing
of command line arguments. This is only a vulnerability in limited
scenarios in which TCPTrack is “configured as a handler for other
applications.”

Impact
======

A remote attacker could possibly execute arbitrary code with the
privileges of the process or cause a Denial of Service condition with a
specially crafted command-line argument.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All TCPTrack users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=net-analyzer/tcptrack-1.4.2”

NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since August 06, 2011. It is likely that your system is
already no longer affected by this issue.
