Category:Red Hat Local Security Checks
Title:RedHat Update for openswan RHSA-2011:1356-01
Summary:The remote host is missing an update for the 'openswan'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'openswan'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.

Affected Software/OS:
openswan on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
