RHEL 6 : openswan (RHSA-2011:1356)

Synopsis :

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

Description :

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.
