<background>
<p>TCPTrack is a simple libpcap based program for live TCP connection
monitoring.
</p>
</background>
<description>
<p>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.”
</p>
</description>
<impact type="normal">
<p>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.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All TCPTrack users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-analyzer/tcptrack-1.4.2"
</code>
<p>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.
