An update that solves three vulnerabilities and has one security fix can now be installed.

Description:

This update for bind fixes the following issues:

• Amended documentation referring to rule types "krb5-subdomain" and "ms-subdomain". This incorrect documentation could mislead operators into believing that policies they had configured were more restrictive than they actually were. [CVE-2018-5741]
• Further limit the number of queries that can be triggered from a request. Root and TLD servers are no longer exempt from max-recursion-queries. Fetches for missing name server address records are limited to 4 for any domain. [CVE-2020-8616]

• Replaying a TSIG BADTIME response as a request could trigger an assertion failure. [CVE-2020-8617] [bsc#1109160, bsc#1171740, CVE-2018-5741, bind-CVE-2018-5741.patch, CVE-2020-8616, bind-CVE-2020-8616.patch, CVE-2020-8617, bind-CVE-2020-8617.patch]

• Don't rely on /etc/insserv.conf anymore for proper dependencies against nss-lookup.target in named.service and lwresd.service (bsc#1118367 bsc#1118368)

• Using a drop-in file
