Red Hat Security Advisory

 

Synopsis: Important: openswan security update

Advisory ID: RHSA-2009:0402-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0402.html

Issue date: 2009-03-30

CVE Names: CVE-2008-4190 CVE-2009-0790

=====================================================================

 

1. Summary:

 

Updated openswan packages that fix various security issues are now

available for Red Hat Enterprise Linux 5.

 

This update has been rated as having important security impact by the Red

Hat Security Response Team.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

 

3. Description:

 

Openswan is a free implementation of Internet Protocol Security (IPsec)

and Internet Key Exchange (IKE). IPsec uses strong cryptography to provide

both authentication and encryption services. These services allow you to

build secure tunnels through untrusted networks. Everything passing through

the untrusted network is encrypted by the IPsec gateway machine, and

decrypted by the gateway at the other end of the tunnel. The resulting

tunnel is a virtual private network (VPN).

 

Gerd v. Egidy discovered a flaw in the Dead Peer Detection (DPD) in

Openswan's pluto IKE daemon. A remote attacker could use a malicious DPD

packet to crash the pluto daemon. (CVE-2009-0790)

 

It was discovered that Openswan's livetest script created temporary files

in an insecure manner. A local attacker could use this flaw to overwrite

arbitrary files owned by the user running the script. (CVE-2008-4190)

 

Note: The livetest script is an incomplete feature and was not

automatically executed by any other script distributed with Openswan, or

intended to be used at all, as was documented in its man page. In these

updated packages, the script only prints an informative message and exits

immediately when run.

 

All users of openswan are advised to upgrade to these updated packages,

which contain backported patches to correct these issues. After installing

this update, the ipsec service will be restarted automatically.

 

4. Solution:

 

Before applying this update, make sure that all previously-released

errata relevant to your system have been applied.
