An update that solves one vulnerability and has three security fixes can now be installed.

Description:

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).
