Detail

Synopsis

Multiple vulnerabilities have been found in Ettercap, the worst of which may allow execution of arbitrary code.

Background

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

Description

Multiple vulnerabilities have been discovered in Ettercap:

* Ettercap does not handle temporary files securely (CVE-2010-3843).
* A format string flaw in Ettercap could cause a buffer overflow (CVE-2010-3844).
* A stack-based buffer overflow exists in Ettercap (CVE-2013-0722).

Impact

A remote attacker could entice a user to load a specially crafted configuration file using Ettercap, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All Ettercap users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/ettercap-0.7.5.2"
