This update for bind fixes the following issues :

CVE-2021-25214: Fixed a broken inbound incremental zone update (IXFR) which could have caused named to terminate unexpectedly (bsc#1185345).

CVE-2021-25215: Fixed an assertion check which could have failed while answering queries for DNAME records that required the DNAME to be processed to resolve itself (bsc#1185345).

MD5 warning message using host, dig, nslookup (bind-utils) on SLES 12 SP5 with FIPS enabled (bsc#1181495).

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.
