Synopsis

The remote SUSE host is missing one or more security updates.

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

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
