Summary
Security update for libgcrypt
Details

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.
