Synopsis
========

A NULL pointer dereference in Openswan may allow remote attackers to
cause Denial of Service.

Background
==========

Openswan is an implementation of IPsec for Linux.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-misc/openswan          <= 2.6.39-r1               Vulnerable!
    -------------------------------------------------------------------
     NOTE: Certain packages are still vulnerable. Users should migrate
           to another package if one is available or wait for the
           existing packages to be marked stable by their
           architecture maintainers.

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

A NULL pointer dereference has been found in Openswan.

Impact
======

A remote attacker could create a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

Gentoo has discontinued support for Openswan. We recommend that users
unmerge Openswan:

  # emerge --unmerge "net-misc/openswan"

NOTE: The Gentoo developer(s) maintaining Openswan have discontinued
support at this time. It may be possible that a new Gentoo developer
will update Openswan at a later date. Alternatives packages such as
Libreswan and strongSwan are currently available in Gentoo Portage.
