Announcement ID: SUSE-SU-2015:0281-1
Rating: moderate
References: #856322 #897048 #897512 #910491
Affected Products:
  • SUSE Linux Enterprise Server 12
  • SUSE Linux Enterprise Desktop 12

  • An update that solves one vulnerability and has three fixes is now available.

    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).
