## Description

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.
