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
