Synopsis
========

An insecure temporary file usage has been reported in Openswan,
allowing for symlink attacks.

Background
==========

Openswan is an implementation of IPsec for Linux.

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

    -------------------------------------------------------------------
     Package            /   Vulnerable   /                  Unaffected
    -------------------------------------------------------------------
  1  net-misc/openswan      < 2.4.13-r2                   >= 2.4.13-r2

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

Dmitry E. Oboukhov reported that the IPSEC livetest tool does not
handle the ipseclive.conn and ipsec.olts.remote.log temporary files
securely.

Impact
======

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

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Openswan users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-misc/openswan-2.4.13-r2"
