    Description:
    
       This update for unbound fixes the following issues:
    
       - CVE-2020-12662: Fixed an issue where unbound could have been tricked
         into amplifying an incoming query into a large number of queries
         directed to a target (bsc#1171889).
       - 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).
