The remote Red Hat host is missing one or more security updates.
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.
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.
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
