  Security issues fixed:

  - CVE-2019-12904: The C implementation of AES is vulnerable to a
  flush-and-reload side-channel attack because physical addresses are
  available to other processes. (The C implementation is used on platforms
  where an assembly-language implementation is unavailable.) (bsc#1138939)

  Other bugfixes:

  - Don't run full FIPS self-tests from constructor (bsc#1097073)

  - Skip all the self-tests except for binary integrity when called from the
  constructor (bsc#1097073)

  - Enforce the minimal RSA keygen size in fips mode (bsc#1125740)

  - avoid executing some tests twice.

  - Fixed a race condition in initialization.

  - Fixed env-script-interpreter in cavs_driver.pl

  - Fixed redundant fips tests in some situations causing failure to boot in
  fips mode. (bsc#1097073)

  This helps during booting of the system in FIPS mode with insufficient
  entropy.
