Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2010:0892 :

Updated openswan packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

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.

Two buffer overflow flaws were found in the Openswan client-side XAUTH
handling code used when connecting to certain Cisco gateways. A
malicious or compromised VPN gateway could use these flaws to execute
arbitrary code on the connecting Openswan client. (CVE-2010-3302,
CVE-2010-3308)

Two input sanitization flaws were found in the Openswan client-side
handling of Cisco gateway banners. A malicious or compromised VPN
gateway could use these flaws to execute arbitrary code on the
connecting Openswan client. (CVE-2010-3752, CVE-2010-3753)

Red Hat would like to thank the Openswan project for reporting these
issues. Upstream acknowledges D. Hugh Redelmeier and Paul Wouters as
the original reporters.

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.
