Scientific Linux Security Update : openswan on SL6.x i386/x86_64

medium Nessus Plugin ID 61149

Language:

Synopsis

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

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)

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

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