Title: IPsec-Tools: authentication bug in racoon
Date: June 22, 2004
Bugs: #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 | Vulnerable | Unaffected |
| 1 net-firewall/ipsec-tools | < 0.3.3 | >= 0.3.3 |
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:
# emerge sync
# emerge -pv ">=net-firewall/ipsec-tools-0.3.3"
# emerge ">=net-firewall/ipsec-tools-0.3.3"
