RHBA-2012:0339 - openswan bug fix update

Synopsis

openswan bug fix update

Type/Severity

Bug Fix Advisory

Topic

An updated openswan package that fixes various bugs is now available for Red Hat Enterprise Linux 6.

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. Openswan supports the NETKEY/XFRM IPsec kernel stack that exists in the default Linux kernel. Openswan 2.6.x also supports IKEv2 (RFC4306).

This updated openswan package includes fixes for the following bugs:

  • The Openswan IKEv2 implementation did not correctly process an IKE_SA_INIT message containing an INVALID_KE_PAYLOAD Notify Payload. With this fix, Openswan now sends the INVALID_KE_PAYLOAD notify message back to the peer so that IKE_SA_INIT can restart with the correct KE payload. (BZ#786434)

  • Previously, Openswan sometimes generated a KE payload that was 1 byte shorter than specified by the Diffie-Hellman algorithm. Consequently, IKE renegotiation failed at random intervals. An error message in the following format was logged:

    next payload type of ISAKMP Identification Payload has an unknown value:

This update checks the length of the generated key and if it is shorter than required, leading zero bytes are added. (BZ#786435)

All users of openswan are advised to upgrade to this updated package, which fixes these bugs. Note that the NSS library package needs to be version 3.13 or later for the KE payload and IKE renegotiation issues to be fully resolved.

Solution

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