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.
