Synopsis
========
A format string vulnerability in Ettercap could allow a remote attacker
to execute arbitrary code.
Background
==========
Ettercap is a suite of tools for content filtering, sniffing and man in
the middle attacks on a LAN.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-analyzer/ettercap < 0.7.3 >= 0.7.3
Description
===========
The curses_msg function of Ettercap's Ncurses-based user interface
insecurely implements formatted printing.
Impact
======
A remote attacker could craft a malicious network flow that would
result in executing arbitrary code with the rights of the user running
the Ettercap tool, which is often root.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Ettercap users should upgrade to the latest available version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/ettercap-0.7.3"
