Synopsis
========

An insecure temporary file usage has been reported in Honeyd, possibly
leading to symlink attacks.

Background
==========

Honeyd is a small daemon that creates virtual hosts on a network.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /  Vulnerable  /                  Unaffected

  1  net-analyzer/honeyd      < 1.5c-r1                     >= 1.5c-r1

Description
===========

Dmitry E. Oboukhov reported an insecure temporary file usage within the
"test.sh" script.

Impact
======

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

Workaround
==========

There is no known workaround at this time.

Resolution

All Honeyd users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/honeyd-1.5c-r1"
