Fri Dec 3 07:52:38 UTC 2021 - Josef Möllers <josef.moellers@suse.com>
- Upgrade to 9.16.23
Security issues fixed:
The "lame-ttl" option is now forcibly set to 0. This
effectively disables the lame server cache, as it could
previously be abused by an attacker to significantly
degrade resolver performance. (CVE-2021-25219)
Bugs fixed:
In 9.16.21:
* When a dynamic zone was made available in another view
using the "in-view" statement, running "rndc freeze"
always reported an "already frozen" error even though
the zone was successfully frozen.
* Stale data in the cache could cause named to send
non-minimized queries despite QNAME minimization being
enabled.
* When a DNSSEC-signed zone which only has a single
signing key available is migrated to use KASP, that key
is now treated as a Combined Signing Key (CSK).
* When a member zone was removed from a catalog zone,
journal files for the former were not deleted.
* named-checkconf failed to detect syntactically invalid
values of the "key" and "tls" parameters used to define
members of remote server lists.
* Fixed a regression which caused the EDNS TCP Keepalive option to be
ignored inadvertently in client requests. It has now
been fixed and this option is handled properly again.
* Fixed a regression which altered the internal memory structure of
zone databases, but neglected to update the MAPAPI value
for zone files in "map" format. This caused named to
attempt to load incompatible map files, triggering an
assertion failure on startup. The MAPAPI value has now
been updated, so named rejects outdated files when
encountering them.
* The thread-local isc_tid_v variable was not properly
initialized when running BIND 9 as a Windows Service,
leading to a crash on startup.
* "map" files exceeding 2GB in size failed to load due to
a size comparison that incorrectly treated the file size
as a signed integer.
In 9.16.22:
* Remove the "adjust interface" mechanism which was
responsible for setting up listeners on interfaces when
the "*-source(-v6)" address and port were the same as
the "listen-on(-v6)" address and port. Such a
configuration is no longer supported; under certain
timing conditions, that mechanism could prevent named
from listening on some TCP ports. This has been fixed.
* Multiple library names were mistakenly passed to the
krb5-config utility when ./configure was invoked with
the --with-gssapi=[/path/to/]krb5-config option. This
has been fixed by invoking krb5-config separately for
each required library.
* Fixed a regression which broke backward compatibility for the
"check-names master ..." and "check-names slave ..."
options. This has been fixed.
* Address a potential deadlock when checking zone content
consistency.
In 9.16.23:
* Address Coverity warning in lib/dns/dnssec.c.
* Fix a bug when comparing two RSA keys. There was a typo
which caused the "p" prime factors to not being
compared.
* Fix an assertion failure caused by missing member zones
during a reload of a catalog zone.
This obsoletes bind-CVE-2021-25219.patch and
bind-fix-build-with-older-sphinx.patch
Other issues:
A compile time waring about fall through in a switch statement
has been averted by marking the cases as FALLTHROUGH.
