Posted by Team   
Fedora When configured to use X.509 certificates to authenticate remote hosts, ipsec-tools versions 0.3.3 and earlier will not abort the key exchange if the verification fails.

Fedora Update Notification

Product     : Fedora Core 2
Name        : ipsec-tools
Version     : 0.2.5                      
Release     : 4                  
Summary     : Tools for configuring and using IPSEC
Description :
This is the IPsec-Tools package.  You need this package in order to
really use the IPsec functionality in the linux-2.5+ kernels.  This
package builds:

        - libipsec, a PFKeyV2 library
	- setkey, a program to directly manipulate policies and SAs
	- racoon, an IKEv1 keying daemon

Update Information:

When configured to use X.509 certificates to authenticate remote
hosts, ipsec-tools versions 0.3.3 and earlier will attempt to verify
that host certificate, but will not abort the key exchange if the
verification fails.

Users of ipsec-tools should upgrade to this updated package which
contains a backported security patch and is not vulnerable to this

* Fri Jun 25 2004 Nalin Dahyabhai <> 0.2.5-4

- backport certificate validation fixes from 0.3.3 (#126568)

* Tue Jun 15 2004 Elliot Lee <>

- rebuilt
