  script_tag(name:"insight", value:"This update for bind fixes the following issues:

BIND was upgraded to version 9.16.6:

Note:

bind is now more strict in regards to DNSSEC. If queries are not
 working, check for DNSSEC issues. For instance, if bind is used in a
 namserver forwarder chain, the forwarding DNS servers must support
 DNSSEC.

Fixing security issues:

CVE-2020-8616: 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. (bsc#1171740)
 Address records are limited to 4 for any domain.

CVE-2020-8617: Replaying a TSIG BADTIME response as a request could
 trigger an assertion failure. (bsc#1171740)

CVE-2019-6477: Fixed an issue where TCP-pipelined queries could bypass
 the tcp-clients limit (bsc#1157051).

CVE-2018-5741: Fixed the documentation (bsc#1109160).

CVE-2020-8618: It was possible to trigger an INSIST when determining
 whether a record would fit into a TCP message buffer (bsc#1172958).

CVE-2020-8619: It was possible to trigger an INSIST in
 lib/dns/rbtdb.c:new_reference() with a particular zone content and query
 patterns (bsc#1172958).

CVE-2020-8624: 'update-policy' rules of type 'subdomain' were
 incorrectly treated as 'zonesub' rules, which allowed keys used in
 'subdomain' rules to update names outside
 of the specified subdomains. The problem was fixed by making sure
 'subdomain' rules are again processed as described in the ARM
 (bsc#1175443).

CVE-2020-8623: When BIND 9 was compiled with native PKCS#11 support, it
 was possible to trigger an assertion failure in code determining the
 number of bits in the PKCS#11 RSA public key with a specially crafted
 packet (bsc#1175443).

CVE-2020-8621: named could crash in certain query resolution scenarios
 where QNAME minimization and forwarding were both enabled (bsc#1175443).

CVE-2020-8620: It was possible to trigger an assertion failure by
 sending a specially crafted large TCP DNS message (bsc#1175443).

CVE-2020-8622: It was possible to trigger an assertion failure when
 verifying the response to a TSIG-signed request (bsc#1175443).

Other issues fixed:

Add engine support to OpenSSL EdDSA implementation.

Add engine support to OpenSSL ECDSA implementation.

Update PKCS#11 EdDSA implementation to PKCS#11 v3.0.

Warn about AXFR streams with inconsistent message IDs.

Make ISC rwlock implementation the default again.

Fixed issues when using cookie-secrets for AES and SHA2 (bsc#1161168)

Installed the default files in /var/lib/named and created chroot
 environment on systems using transactional-updates (bsc#1100369,
 fate#325524)

Fixed an issue where bind was not working in FIPS mode (bsc#906079).

Fixed dependency issues (bsc#1118367 and bsc#1118368).

GeoIP support is now discontinued, now GeoIP2 is used(bsc#1156205).

Fixed an issue with FIPS (bsc#1128220).

The liblwres library is discontinued upstream ... [Please see the references for more information on the vulnerabilities]");
