  - CVE-2021-25219: Fixed flaw that allowed abusing lame cache to severely
       degrade resolver performance (bsc#1192146).

  - CVE-2021-25220: Fixed potentially incorrect answers by cached forwarders
       (bsc#1197135).

  - CVE-2022-0396: Fixed a incorrect handling of TCP connection slots time
       frame  leading to deny of service (bsc#1197136).
  The following non-security bugs were fixed:

  - Update to release 9.16.31 (jsc#SLE-24600).

  - Logrotation broken since dropping chroot (bsc#1200685).

  - A non-existent initialization script (eg a leftorver
       'createNamedConfInclude' in /etc/sysconfig/named) may cause named not to
       start. A warning message is printed in named.prep and the fact is
       ignored. Also, the return value of a failed script was not handled
       properly causing a failed script to not prevent named to start. This is
       now fixed properly. [bsc#1199044, vendor-files.tar.bz2]");
