update for strongswan","description":"This strongswan update fixes the following security and non security\nissues.\n\n- Disallow brainpool elliptic curve groups in fips mode (bnc#856322).\n- Applied an upstream fix for a denial-of-service vulnerability,\n  which can be triggered by an IKEv2 Key Exchange payload, that\n  contains the Diffie-Hellman group 1025 (bsc#910491,CVE-2014-9221).\n- Adjusted whilelist of approved algorithms in fips mode (bsc#856322).\n- Updated strongswan-hmac package description (bsc#856322).\n- Disabled explicit gpg validation; osc source_validator does it.\n- Guarded fipscheck and hmac package in the spec file for \u003e13.1.\n- Added generation of fips hmac hash files using fipshmac utility\n  and a _fipscheck script to verify binaries/libraries/plugings\n  shipped in the strongswan-hmac package.\n  With enabled fips in the kernel, the ipsec script will call it\n  before any action or in a enforced/manual 'ipsec _fipscheck' call.\n  Added config file to load openssl and kernel af-alg plugins, but\n  not all the other modules which provide further/alternative algs.\n  Applied a filter disallowing non-approved algorithms in fips mode.\n  (fate#316931,bnc#856322).\n- Fixed file list in the optional (disabled) strongswan-test package.\n- Fixed build of the strongswan built-in integrity checksum library\n  and enabled building it only on architectures tested to work.\n- Fix to use bug number 897048 instead 856322 in last changes entry.\n- Applied an upstream patch reverting to store algorithms in the\n  registration order again as ordering them by identifier caused\n  weaker algorithms to be proposed first by default (bsc#897512).","status":"published","published":"2015-01-28T11:41:44Z","modified":"2026-02-04T03:40:13.664296Z","updated_at":"2026-11-02T15:53:41.276824Z"},{"id":"UBUNTU-CVE-2014-9221","description":"strongSwan
