DESCRIPTION:
A security issue has been discovered in Ettercap, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges.

The security issue is caused due to the application using a
configuration file "/tmp/.ettercap_gtk" in an insecure manner when
running the application with the "-G" option. This can be exploited
to e.g. overwrite arbitrary files via symlink attacks.

NOTE: This can further be exploited to cause a stack-based buffer
overflow due to a boundary error in the "gtkui_conf_read()" function
in src/interfaces/gtk/ec_gtk_conf.c and potentially execute arbitrary
code.

The security issue is confirmed in version 0.7.3 on a Linux system.
Other versions may also be affected.

SOLUTION:
Restrict access to trusted users only.
