>Release:        8.2-P9
>Organization:
>Environment:
FreeBSD fw31.cis 8.2-RELEASE-p6 FreeBSD 8.2-RELEASE-p9
>Description:
I regularly build new releases, and install fresh boxes at the current patch level, e.g. FreeBSD 8.2-P9.

I've found that the instructions in some advisories seem to assume that the maintainer of a box has used previous advisories to maintain that box from a previous patch level, and the instructions aren't necessarily correct as standalone instructions, especially if you have a box that was freshly installed at a particular patch level.

For example, for the latest BIND advisory... http://www.freebsd.org/security/advisories/FreeBSD-SA-12:05.bind.asc -

If you happened to do a clean install of FreeBSD 8.2-P9, and you don't already have libraries built below /usr/src/lib/bind, then running 

# cd /usr/src/lib/bind/dns
# make obj && make depend && make && make install

and then following up with the next set of instructions

# cd /usr/src/usr.sbin/named
# make obj && make depend && make && make install

you'll get several complaints about missing libraries under /usr/src/lib/bind.

I'd argue that the safer set of instructions, not assuming that related libraries under /usr/src/lib/bind/isc, /usr/src/lib/bind/isccc, /usr/src/lib/bind/isccfg, etc... are built would be the following...

# cd /usr/src/lib/bind
# make obj && make depend && make && make install

and then proceeding with

# cd /usr/src/usr.sbin/named
# make obj && make depend && make && make install

Thanks,
- Jason



>How-To-Repeat:
Do a fresh install of FreeBSD 8.2-P9 (assuming that you maintain a release server, and build releases at the current patch level).

Follow instructions for http://www.freebsd.org/security/advisories/FreeBSD-SA-12:05.bind.asc


>Fix:
Don't assume existence of several libraries under /usr/src/lib/bind from previous BIND advisories.

Run the following as the first 'build' step...

# cd /usr/src/lib/bind
# make obj && make depend && make && make install

rather than

# cd /usr/src/lib/bind/dns
# make obj && make depend && make && make install
