Synopsis
========
ipsec-tools contains a vulnerability that affects connections authenticated with X.509 certificates.
Background
==========
From http://ipsec-tools.sourceforge.net/ :
"IPsec-Tools is a port of KAME's IPsec utilities to the Linux-2.6 IPsec implementation."
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
net-firewall/ipsec-tools = 0.2.5
Description
===========
racoon (a utility in the ipsec-tools package) does not verify digital signatures on Phase1 packets. This means that anybody holding the correct X.509 certificate would be able to establish a connection, even if they did not have the corresponding private key.
Impact
======
Since digital signatures are not verified by the racoon tool, an attacker may be able to connect to the VPN gateway and/or execute a man-in-the-middle attack.
Workaround
==========
A workaround is not currently known for this issue. All users are advised to upgrade to the latest version of the affected package.
Resolution
==========
ipsec-tools users should upgrade to version 0.2.5 or later:
# emerge sync
# emerge -pv ">=net-firewall/ipsec-tools-0.2.5"
# emerge ">=net-firewall/ipsec-tools-0.2.5"
Concerns?
=========
Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
