GLSA-200404-05 : ipsec-tools contains an X.509 certificates vulnerability.

high Nessus Plugin ID 14470

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-200404-05 (ipsec-tools contains an X.509 certificates vulnerability.)

 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.

Solution

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'
