Migrate doc to Hugo/AsciiDoctor

I'm very pleased to announce the release of
our new website and documentation using
the new toolchain with Hugo and AsciiDoctor.

To get more information about the new toolchain
please read the FreeBSD Documentation Project Primer[1],
Hugo docs[2] and AsciiDoctor docs[3].

-
-Category:       contrib
-Module:         bzip2
-Announced:      2019-08-06
-Affects:        All supported versions of FreeBSD.
-Corrected:      2019-07-04 07:29:18 UTC (stable/12, 12.0-STABLE)
-                2019-08-06 17:09:47 UTC (releng/12.0, 12.0-RELEASE-p9)

-
-For general information regarding FreeBSD Security Advisories,
-including descriptions of the fields above, security branches, and the
-following sections, please visit <URL:https://security.FreeBSD.org/>.
-
-I.   Background
-
-The bzip2(1)/bunzip2(1) utilities and the libbz2 library compress and
-decompress files using an algorithm based on the Burrows-Wheeler transform.
-They are generally slower than Lempel-Ziv compressors such as gzip, but
-usually provide a greater compression ratio.
-
-The bzip2recover utility extracts blocks from a damaged bzip2(1) file,
-permitting partial recovery of the contents of the file.
-
-II.  Problem Description
-
-The decompressor used in bzip2 contains a bug which can lead to an
-out-of-bounds write when processing a specially crafted bzip2(1) file.
-
-bzip2recover contains a heap use-after-free bug which can be triggered
-when processing a specially crafted bzip2(1) file.
-
-III. Impact
-
-An attacker who can cause maliciously crafted input to be processed
-may trigger either of these bugs.  The bzip2recover bug may cause a
-crash, permitting a denial-of-service.  The bzip2 decompressor bug
-could potentially be exploited to execute arbitrary code.
-
-Note that some utilities, including the tar(1) archiver and the bspatch(1)
-binary patching utility (used in portsnap(8) and freebsd-update(8))
-decompress bzip2(1)-compressed data internally; system administrators should
-assume that their systems will at some point decompress bzip2(1)-compressed
-data even if they never explicitly invoke the bunzip2(1) utility.
-
-IV.  Workaround
-
-No workaround is available.
-
-V.   Solution
-
-Upgrade your vulnerable system to a supported FreeBSD stable or
-release / security branch (releng) dated after the correction date,
-and restart daemons if necessary.
-
-1) To update your vulnerable system via a binary patch:
-
-Systems running a RELEASE version of FreeBSD on the i386 or amd64
-platforms can be updated via the freebsd-update(8) utility:
-
-# freebsd-update fetch
-# freebsd-update install
-
-2) To update your vulnerable system via a source code patch:
-
-The following patches have been verified to apply to the applicable
-FreeBSD release branches.
-
-a) Download the relevant patch from the location below, and verify the
-detached PGP signature using your PGP utility.
-
-# fetch https://security.FreeBSD.org/patches/SA-19:18/bzip2.patch
-# fetch https://security.FreeBSD.org/patches/SA-19:18/bzip2.patch.asc
-# gpg --verify bzip2.patch.asc
-
-b) Apply the patch.  Execute the following commands as root:
-
-# cd /usr/src
-# patch < /path/to/patch
-
-c) Recompile the operating system using buildworld and installworld as
-described in <URL:https://www.FreeBSD.org/handbook/makeworld.html>.
-
-Restart all daemons that use the library, or reboot the system.
-
-VI.  Correction details
-
-The following list contains the correction revision numbers for each
-affected branch.
