RHBA-2011:0388 - Bug Fix Advisory

Topic

Updated openswan packages that fix a bug are now available for Red Hat
Enterprise Linux 5 Extended Update Support.

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.

This update fixes the following bug:

• Due to an error in a buffer initialization, the following message may have

been written to the /var/log/secure log file during the IKE negotiation:

size ([size]) differs from size specified in ISAKMP HDR ([size])

Consequently, the establishment of secure connections could be significantly
delayed. This update applies an upstream patch that resolves this issue, and the
establishment of IPsec connections is is no longer delayed. (BZ#680044)

All users of openswan are advised to upgrade to these updated packages, which
resolve this issue.

Solution

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