  - CVE-2020-12663: Fixed an issue where malformed answers from upstream
  name servers could have been used to make unbound unresponsive
  (bsc#1171889).

  - CVE-2019-18934: Fixed a vulnerability in the IPSec module which could
  have allowed code execution after receiving a special crafted answer
  (bsc#1157268).
