Ettercap: Format string vulnerability — GLSA 200506-07

A format string vulnerability in Ettercap could allow a remote attacker to execute arbitrary code.

Affected Packages

net-analyzer/ettercap on all architectures
Affected versions < 0.7.3

Background

Ettercap is a suite of tools for content filtering, sniffing and man in the middle attacks on a LAN.

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"
