Summary: Security update for bind

Details: 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]
