From Upstream Release notes:
Security Fixes
DNS rebinding protection was ineffective when BIND 9 is configured as a forwarding DNS server. Found and responsibly reported by Tobias Klein. [GL #1574]
Known Issues
We have received reports that in some circumstances, receipt of an IXFR can cause the processing of queries to slow significantly. Some of these were related to RPZ processing, which has been fixed in this release (see below). Others appear to occur where there are NSEC3-related changes (such as an operator changing the NSEC3 salt used in the hash calculation). These are being investigated. [GL #1685]
Unlike other build dependencies, no public headers include from
libmaxminddb any symbols. That means no build would ever fail
if libmaxminddb-devel package is not installed. Do not require it when
installing bind-lite-devel but keep the requirement when building from
sources.
Has to be enabled in build by --with TSAN.
Would make build fail unit tests and print many warnings about possible
race conditions. Not useful for production build, but useful for
debugging thread related problems in system tests.
It might not fix all issues, but was detected by upstream using
automated tool. Should not break anything new, but might fix issue
triggered usually on ppc64le platform.
Previous fix included just part inside named. However, checking part
would check algorithm support also in check library. The code is almost
the same. Permit already disabled algoritms also in libbind9.
Use the same change as RHEL.
Return failed status code to command. Not only report error message to
the log, but also report reload success. Must not terminate running
service on failed reload.
Use parallel execution on test run. Support already configured
interfaces without special permissions on build. It can either use
already present addresses or configure it on build time. If it has no
rights to configure it, just skip the test and continue.
Few configuration and zone files were moved into tarball by commit
55b04de09a. It makes tracking of changes difficult, hardens rebases,
makes difficult building without proper lookaside cache. Those files are
tiny, no need to hold them inside compressed binary archive. Move them
out.
Replaces also few places with proper directory macros.
Previous build recommended bind-dnssec-utils just to provide manual for
pkcs11 variants. Instead, share the same files between pkcs11-utils and
dnssec-utils. Skip unnecessary manual of non-existent dnssec-coverage-pkcs11 tool.
Manual pages are just links to pages in bind-dnssec-utils. Do not copy
them, but suggest them for installation is possible. It would be handy
to have them available, but are not required for any function.
named can use ACLs defined by GeoIP of request. Such information is not
available by default under named-chroot service. Enable GeoIP databases
under chroot without explicit configuration.
Make it easier to manage list of used directories in chroot. Use
appropriate macros for system directories everywhere in chroot package.
Share common variable with -sdb-chroot and -chroot packages.
Some utilities are not related DNSSEC at all, but are just bind related
tools. Because they do not require additional dependencies, they do not
save any space in containers.
When MD5 is disabled in library, it behaved like RSAMD5 were unknown.
But security-policy disables it explicitly. It failed to even start in
FIPS mode, because such algorithm were unknown. Fix disabled algorithm
to return disabled result code. Accept such algorithm only when
disabling it.
