GLSA-200406-17 : IPsec-Tools: authentication bug in racoon

critical Nessus Plugin ID 14528

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200406-17 (IPsec-Tools: authentication bug in racoon)

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.

Solution

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'
