Fix CVE-2023-3341: The code that processes control channel messages sent
to `named` calls certain functions recursively during packet parsing.
Recursion depth is only limited by the maximum accepted packet size;
depending on the environment, this may cause the packet-parsing code to
run out of available stack memory, causing `named` to terminate
unexpectedly. Since each incoming control channel message is fully
parsed before its contents are authenticated, exploiting this flaw does
not require the attacker to hold a valid RNDC key; only network access
to the control channel's configured TCP port is necessary. This issue
affects BIND 9 versions 9.2.0 through 9.16.43, 9.18.0 through 9.18.18,
9.19.0 through 9.19.16, 9.9.3-S1 through 9.16.43-S1, and 9.18.0-S1
through 9.18.18-S1.

The bind package exhibits gcc bug 101737 when built for the SH4
architecture with optimization enabled, which causes a build failure.
As done for other packages in Buildroot work around this gcc bug by
setting optimization to -O0 if BR2_TOOLCHAIN_HAS_GCC_BUG_101737=y.
To achieve this we need to correct the override of CFLAGS by using:
BIND_CONF_OPTS += CFLAGS="$(BIND_CFLAGS)"
instead of:
BIND_CONF_ENV = BUILD_CFLAGS"$(BIND_CFLAGS)"
since the latter doesn't work as expected and doesn't override CFLAGS.

There had existed in one of the ISC BIND libraries a bug in a
function that was used by dhcpd when operating in DHCPv6 mode.
There was also a bug in dhcpd relating to the use of this function
per its documentation, but the bug in the library function
prevented this from causing any harm. All releases of dhcpd from
ISC contain copies of this, and other, BIND libraries in
combinations that have been tested prior to release and are known
to not present issues like this.
Affects: Builds of dhcpd versions prior to version 4.4.1 when
using BIND versions 9.11.2 or later.

- When recursion is enabled but the allow-recursion and allow-query-cache
ACLs are not specified, they should be limited to local networks, but they

remote queries. This flaw is disclosed in CVE-2018-5738. [GL #309]
- Code change #4964, intended to prevent double signatures when deleting an
inactive zone DNSKEY in some situations, introduced a new problem during
zone processing in which some delegation glue RRsets are incorrectly
identified as needing RRSIGs, which are then created for them using the
current active ZSK for the zone. In some, but not all cases, the
newly-signed RRsets are added to the zone's NSEC/NSEC3 chain, but
incompletely -- this can result in a broken chain, affecting validation of
proof of nonexistence for records in the zone. [GL #771]
- named could crash if it managed a DNSSEC security root with managed-keys
and the authoritative zone rolled the key to an algorithm not supported by
BIND 9. This flaw is disclosed in CVE-2018-5745. [GL #780]
