RHEL 5 / 6 : openswan (RHSA-2014:0185)

medium Nessus Plugin ID 72567

Language:

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 5 and 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 discovered in the way Openswan's IKE daemon processed IKEv2 payloads. A remote attacker could send specially crafted IKEv2 payloads that, when processed, would lead to a denial of service (daemon crash), possibly causing existing VPN connections to be dropped. (CVE-2013-6466)

All openswan users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

Solution

Update the affected openswan, openswan-debuginfo and / or openswan-doc packages.
