For general information regarding FreeBSD Errata Notices and Security
Advisories, including descriptions of the fields above, security
branches, and the following sections, please visit
<URL:https://security.FreeBSD.org/>.
I. Background
The freebsd-update(8) utility is used to apply binary patches to FreeBSD
systems installed from official release images, as an alternative to
rebuilding from source.
II. Problem Description
The recent development of FreeBSD has introduced additional release
distribution names, which would fail with the existing freebsd-update(8)
sanity checks.
III. Impact
Upgrading to FreeBSD 11.x from existing FreeBSD releases is not possible
due failing sanity checks.
IV. Workaround
No workaround is available other than patching the freebsd-update(8)
utility, but systems that do not use FreeBSD-provided binary updates
to upgrade are not affected.
V. Solution
Perform one of the following:
1) Upgrade your system to a supported FreeBSD stable or release / security
branch (releng) dated after the correction date.
A reboot is not required.
2) To update your 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
A reboot is not required.
Please note that for FreeBSD 11.0-BETA1, the freebsd-update utility needs
to be patched manually.
# fetch http://update.freebsd.org/11.0-BETA1/i386/f/6b42aa5e560601bbf30c0b7a6ceed274796c955e6254f7a2fcd393376fe21c55.gz
# gunzip -c < 6b42aa5e560601bbf30c0b7a6ceed274796c955e6254f7a2fcd393376fe21c55.gz > NEW
# sha256 -q NEW
Verify that the output is:
6b42aa5e560601bbf30c0b7a6ceed274796c955e6254f7a2fcd393376fe21c55
# install -m 555 NEW /usr/sbin/freebsd-update
3) To update your 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/EN-16:09/freebsd-update.patch
# fetch https://security.FreeBSD.org/patches/EN-16:09/freebsd-update.patch.asc
# gpg --verify freebsd-update.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>.
