LOW Confidentiality impact
HIGH Integrity impact
HIGH Availability impact
HIGH Summary
The GTK version of ettercap uses a global settings file at /tmp/.ettercap_gtk and does not verify ownership of this file. When parsing this file for settings in gtkui_conf_read() (src/interfacesgtk/ec_gtk_conf.c), an unchecked sscanf() call allows a maliciously placed settings file to overflow a statically-sized buffer on the stack.

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. last seen 2020-06-01 modified 2020-06-02 plugin id 74055 published 2014-05-19 reporter This script is Copyright (C) 2014-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/74055 title GLSA-201405-12 : Ettercap: Multiple vulnerabilities
