       An update that solves one vulnerability and has two fixes
       is now available.
    
    Description:
    
       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.
