  script_tag(name:"insight", value:"This strongswan update fixes the following security and non security issues.

- Disallow brainpool elliptic curve groups in fips mode (bnc#856322).
- 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 (bsc#856322).
- Updated strongswan-hmac package description (bsc#856322).
- Disabled explicit gpg validation, osc source_validator does it.
- Guarded fipscheck and hmac package in the spec file for >13.1.
- 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.
 (fate#316931,bnc#856322).
- 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).");
