Gentoo Linux Security Advisory

Title: IPsec-Tools: authentication bug in racoon (GLSA 200406-17)
Severity: normal
Exploitable: remote
Date: June 22, 2004
Updated: May 22, 2006
Bug(s): #53915
ID: 200406-17

Synopsis

racoon provided as part of IPsec-Tools fails do proper authentication.

Background

IPsec-Tools is a port of KAME's implementation of the IPsec utilities. It contains a collection of network monitoring tools, including racoon, ping, and ping6.

Affected Packages

Package: net-firewall/ipsec-tools
Vulnerable: < 0.3.3
Unaffected: >= 0.3.3
Architectures: All supported architectures


Description

The KAME IKE daemon racoon is used to authenticate peers during Phase 1 when using either preshared keys, GSS-API, or RSA signatures. When using RSA signatures racoon validates the X.509 certificate but not the RSA signature.

Impact

By sending a valid and trusted X.509 certificate and any private key an attacker could exploit this vulnerability to perform man-in-the-middle attacks and initiate unauthorized connections.

Workaround

There is no known workaround at this time. All users are encouraged to upgrade to the latest available version.

Resolution

All IPsec-Tools users should upgrade to the latest stable version:
Code:
# emerge sync
# emerge -pv ">=net-firewall/ipsec-tools-0.3.3"
# emerge ">=net-firewall/ipsec-tools-0.3.3"
