RHBA-2009:1612 - openswan bug fix update

Synopsis

openswan bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated openswan packages that fix an issue and enable Openswan to pass the TAHI test suite for HMAC-SHA1-96 support are now available.

Description

Openswan is a free implementation of Internet Protocol Security (IPsec) and Internet Key Exchange (IKE) for Linux. IPsec uses strong cryptography to provide both authentication and encryption services. These services allow you to build secure tunnels through untrusted networks. Everything passing through the untrusted net is encrypted by the IPsec gateway machine and decrypted by the gateway at the other end of the tunnel. The resulting tunnel is a virtual private network, or VPN.

These packages contain the daemons and userland tools for setting up Openswan. They support the NETKEY/XFRM IPsec stack in the default Linux kernel. The Openswan 2.6.x-series also supports IKEv2 as described in RFC 4309.

The TAHI Project IPv6 Ready Test Suite, Phase 2, includes an IKE version 2 test category. Support for the HMAC-SHA1-96 message digest algorithm is required by this category and, previously, Openswan did not include such support. With this update, HMAC-SHA1-96 supported has been added to the openswan package. (BZ#533883)

This update fixes the following issue:

  • the FIPS-140-2 standard requires cryptographic modules to provide methods to "zeroize" (meaning: to overwrite with zeroes) all plain text secret and private cryptographic keys and Critical Security Parameters (CSPs). With this update, Openswan uses methods supplied by the NSS library to perform zeroization on plain text secret and private cryptographic keys and CSPs.

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

Solution
