Oracle Linux 6 : openswan (ELSA-2011-1356)

Medium Nessus Plugin ID 68365


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


From Red Hat Security Advisory 2011:1356 :

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

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link 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.

A NULL pointer dereference flaw was found in the way Openswan's pluto IKE daemon handled certain error conditions. A remote, unauthenticated attacker could send a specially crafted IKE packet that would crash the pluto daemon. (CVE-2011-3380)

Red Hat would like to thank the Openswan project for reporting this issue. Upstream acknowledges Paul Wouters as the original reporter.

All users of openswan are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
After installing this update, the ipsec service will be restarted automatically.


Update the affected openswan packages.
