   An update that solves three vulnerabilities, contains one
   feature and has two fixes is now available.

Description:

   This update for bind fixes the following issues:

   - 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]
