Synopsis

Moderate: openswan security update

Type/Severity

Security Advisory: Moderate

Topic

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.

Description

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.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
