SUSE SLED12 / SLES12 Security Update : strongswan (SUSE-SU-2015:0281-1)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.

Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

This strongswan update fixes the following security and non security

- Disallow brainpool elliptic curve groups in fips mode

- Applied an upstream fix for a denial-of-service
vulnerability, which can be triggered by an IKEv2 Key
Exchange payload, that contains the Diffie-Hellman group
1025 (bsc#910491,CVE-2014-9221).

- Adjusted whilelist of approved algorithms in fips mode

- Updated strongswan-hmac package description

- Disabled explicit gpg validation; osc source_validator
does it.

- Guarded fipscheck and hmac package in the spec file for

- Added generation of fips hmac hash files using fipshmac
utility and a _fipscheck script to verify
binaries/libraries/plugings shipped in the
strongswan-hmac package. With enabled fips in the
kernel, the ipsec script will call it before any action
or in a enforced/manual 'ipsec _fipscheck' call. Added
config file to load openssl and kernel af-alg plugins,
but not all the other modules which provide
further/alternative algs. Applied a filter disallowing
non-approved algorithms in fips mode.

- Fixed file list in the optional (disabled)
strongswan-test package.

- Fixed build of the strongswan built-in integrity
checksum library and enabled building it only on
architectures tested to work.

- Fix to use bug number 897048 instead 856322 in last
changes entry.

- Applied an upstream patch reverting to store algorithms
in the registration order again as ordering them by
identifier caused weaker algorithms to be proposed first
by default (bsc#897512).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
