"This update for libgcrypt fixes the following issues :

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.
