BIND 9.4.3-P4 is a SECURITY PATCH for BIND 9.4.3. It addresses a
potential cache poisoning vulnerability, in which data in the additional
section of a response could be cached without proper DNSSEC validation.
Changes since 9.4.3-P3:
2772. [security] When validating, track whether pending data was from
the additional section or not and only return it if
validates as secure. [RT #20438]
BIND 9.4.3-P5 is a SECURITY PATCH for BIND 9.4.3. It addresses two
potential cache poisoning vulnerabilities, both of which could allow
a validating recursive nameserver to cache data which had not been
authenticated or was invalid.
CVE identifiers: CVE-2009-4022, CVE-2010-0097
CERT advisories: VU#418861, VU#360341
Changes since 9.4.3-P4:
2831. [security] Do not attempt to validate or cache
out-of-bailiwick data returned with a secure
answer; it must be re-fetched from its original
source and validated in that context. [RT #20819]
2828. [security] Cached CNAME or DNAME RR could be returned to clients
without DNSSEC validation. [RT #20737]
2827. [security] Bogus NXDOMAIN could be cached as if valid. [RT #20712]

2579. [bug] DNSSEC lookaside validation failed to handle unknown
algorithms. [RT #19479]

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

2522. [security] Handle -1 from DSA_do_verify().
2498. [bug] Removed a bogus function argument used with
ISC_SOCKET_USE_POLLWATCH: it could cause compiler
warning or crash named with the debug 1 level
of logging. [RT #18917]

2406. [bug] Some operating systems have FD_SETSIZE set to a
low value by default, which can cause resource
exhaustion when many simultaneous connections are
open. Linux in particular makes it difficult to
increase this value. To use more sockets with
select(), set ISC_SOCKET_FDSETSIZE. Example:
STD_CDEFINES="-DISC_SOCKET_FDSETSIZE=4096" ./configure
(This should not be necessary in most cases, and
never for an authoritative-only server.) [RT #18328]
2404. [port] hpux: files unlimited support.
2403. [bug] TSIG context leak. [RT #18341]
2402. [port] Support Solaris 2.11 and over. [RT #18362]
2401. [bug] Expect to get E[MN]FILE errno internal_accept()
(from accept() or fcntl() system calls). [RT #18358]
2399. [bug] Abort timeout queries to reduce the number of open
UDP sockets. [RT #18367]
2398. [bug] Improve file descriptor management. New,
temporary, named.conf option reserved-sockets,
default 512. [RT #18344]
2396. [bug] Don't set SO_REUSEADDR for randomized ports.
[RT #18336]
2395. [port] Avoid warning and no effect from "files unlimited"
on Linux when running as root. [RT #18335]
2394. [bug] Default configuration options set the limit for
open files to 'unlimited' as described in the
documentation. [RT #18331]
2392. [bug] remove 'grep -q' from acl test script, some platforms
don't support it. [RT #18253]
2322. [port] MacOS: work around the limitation of setrlimit()
for RLIMIT_NOFILE. [RT #17526]

and to support the "inet6" option instead.
Remaining usage of USE_INET6 was solely for the benefit of the scripts
that generate the README.html files. Replace:
BUILD_DEFS+= USE_INET6
with
BUILD_DEFS+= IPV6_READY
and teach the README-generation tools to look for that instead.
This nukes USE_INET6 from pkgsrc proper. We leave a tiny bit of code
to continue to support USE_INET6 for pkgsrc-wip until it has been nuked
from there as well.

"allow-query-cache" and "allow-recursion" now
cross inherit from each other.
If allow-query-cache is not set in named.conf then
allow-recursion is used if set, otherwise allow-query
is used if set, otherwise the default (localnets;
localhost;) is used.
If allow-recursion is not set in named.conf then
allow-query-cache is used if set, otherwise allow-query
is used if set, otherwise the default (localnets;
localhost;) is used.
2203. [security]
Query id generation was cryptographically weak.

the owner of all installed files is a non-root user. This change
affects most packages that require special users or groups by making
them use the specified unprivileged user and group instead.
(1) Add two new variables PKG_GROUPS_VARS and PKG_USERS_VARS to
unprivileged.mk. These two variables are lists of other bmake
variables that define package-specific users and groups. Packages
that have user-settable variables for users and groups, e.g. apache
and APACHE_{USER,GROUP}, courier-mta and COURIER_{USER,GROUP},
etc., should list these variables in PKG_USERS_VARS and PKG_GROUPS_VARS
so that unprivileged.mk can know to set them to ${UNPRIVILEGED_USER}
and ${UNPRIVILEGED_GROUP}.
(2) Modify packages to use PKG_GROUPS_VARS and PKG_USERS_VARS.

CVE-2007-2241: A sequence of queries can cause a recursive nameserver
to exit. While it is unlikely these will occur in normal operation, an
attack can use them to cause the affected versions to exit. This attack
is a denial of service, and does not allow an attacker to gain control
of affected systems.

Lots of changes, see http://www.isc.org/sw/bind/view/?release=9.3.4#RELEASE
for all the details:
In brief:
2126. [security] Serialise validation of type ANY responses.
2124. [security] It was possible to dereference a freed fetch
context.
2089. [security] Raise the minimum safe OpenSSL versions to
OpenSSL 0.9.7l and OpenSSL 0.9.8d. Versions
prior to these have known security flaws which
are (potentially) exploitable in named.
2088. [security] Change the default RSA exponent from 3 to 65537.
2066. [security] Handle SIG queries gracefully.
1941. [bug] ncache_adderesult() should set eresult even if no
rdataset is passed to it.

* Assertion failure in ISC BIND SIG query processing (CVE-2006-4095)
- Recursive servers
Queries for SIG records will trigger an assertion failure if more
than one RRset is returned. However exposure can be minimized by
restricting which sources can ask for recursion.
- Authoritative servers
If a nameserver is serving a RFC 2535 DNSSEC zone and is queried
for the SIG records where there are multiple RRsets, then the
named program will trigger an assertion failure when it tries
to construct the response.
* INSIST failure in ISC BIND recursive query handling code (CVE-2006-4096)
It is possible to trigger an INSIST failure by sending enough
recursive queries such that the response to the query arrives after
all the clients waiting for the response have left the recursion
queue. However exposure can be minimized by restricting which sources
can ask for recursion.

Fix build on NetBSD/sparc64 3.x: sync CPP symbols usage between
struct addrinfo definition and its usage in getaddrinfo().
While here define struct addrinfo's pad members the same way as in
NetBSD's /usr/include/netbsd.h and sync code in
lib/bind/irs/getaddrinfo.c:getaddrinfo().
This had been reported to bind9-bugs at isc dot org.

and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto

of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.

dutifully installs whatever it thinks might be missing or just
substandard on the current system.
As the Makefile already adds the contents of share/doc/bind9
dynamically to the PLIST, do the same for include/bind.
Fixes the PLIST on RedHat EL 2 & 3, and does not break it on NetBSD/3
No PKGREVISION bump as no change to anything but generated PLIST

RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
