Vulnerability Assessment Details

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

Vulnerability Assessment Summary
ipsec-tools contains an X.509 certificates vulnerability.

Detailed Explanation for this Vulnerability Assessment
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, a possible hacker 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"
