"This update of libgcrypt fixes one security issue and brings various
FIPS 140-2 related improvements.

libgcrypt now uses ciphertext blinding for Elgamal decryption
(CVE-2014-3591)

FIPS 140-2 related changes :

  - The library performs its self-tests when the module is
    complete (the

    -hmac file is also installed).

  - Added a NIST 800-90a compliant DRBG.

  - Change DSA key generation to be FIPS 186-4 compliant.

  - Change RSA key generation to be FIPS 186-4 compliant.

  - Enable HW support in fips mode (bnc#896435)

  - Make DSA selftest use 2048 bit keys (bnc#898003)

  - Added ECDSA selftests and add support for it to the CAVS
    testing framework (bnc#896202)

  - Various CAVS testing improvements.

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
without introducing additional issues."
