GLSA 201402-22: TCPTrack: Arbitrary code execution

Severity:normal
Title:TCPTrack: Arbitrary code execution
Date:02/21/2014
Bugs: #377917
ID:201402-22

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 Architecture(s)
net-analyzer/tcptrack < 1.4.2 >= 1.4.2 All supported architectures

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.
