FreeBSD-SA-16:27.openssl Security Advisory
The FreeBSD Project
Topic: Regression in OpenSSL suite
Category: contrib
Module: openssl
Announced: 2016-10-10
Credits: OpenSSL Project
-Affects: All supported versions of FreeBSD.
+Affects: FreeBSD 11.0
Corrected: 2016-09-26 14:30:19 UTC (stable/11, 11.0-STABLE)
2016-09-26 20:26:19 UTC (releng/11.0, 11.0-RELEASE-p1)
CVE Name: CVE-2016-7052
For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit .
I. Background
FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is
a collaborative effort to develop a robust, commercial-grade, full-featured
Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3)
and Transport Layer Security (TLS v1) protocols as well as a full-strength
general purpose cryptography library.
II. Problem Description
The OpenSSL version included in FreeBSD 11.0-RELEASE is 1.0.2i. The version
has bug fix for CVE-2016-7052, which should have included CRL sanity check,
but the check was omitted.
III. Impact
Any attempt to use CRLs in OpenSSL 1.0.2i will crash with a null pointer
exception.
IV. Workaround
No workaround is available.
V. Solution
Perform one of the following:
1) Upgrade your vulnerable system to a supported FreeBSD stable or
release / security branch (releng) dated after the correction date.
Restart all daemons that use the library, or reboot the system.
2) 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
Restart all daemons that use the library, or reboot the system.
3) 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-16:27/openssl.patch
# fetch https://security.FreeBSD.org/patches/SA-16:27/openssl.patch.asc
# gpg --verify openssl.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 .
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.
Branch/path Revision
- -------------------------------------------------------------------------
stable/11/ r306343
releng/11.0/ r306354
- -------------------------------------------------------------------------
To see which files were modified by a particular revision, run the
following command, replacing NNNNNN with the revision number, on a
machine with Subversion installed:
# svn diff -cNNNNNN --summarize svn://svn.freebsd.org/base
Or visit the following URL, replacing NNNNNN with the revision number:

FreeBSD-SA-16:31.libarchive Security Advisory
The FreeBSD Project
Topic: Multiple libarchive vulnerabilities
Category: core
Module: portsnap
Announced: 2016-10-05
Affects: All supported versions of FreeBSD.
Corrected: 2016-09-25 22:02:27 UTC (stable/11, 11.0-STABLE)
2016-09-27 19:36:12 UTC (releng/11.0, 11.0-RELEASE-p1)
2016-09-25 22:04:02 UTC (stable/10, 10.3-STABLE)

For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit .
I. Background
The libarchive(3) library provides a flexible interface for reading and
writing streaming archive files such as tar(1) and cpio(1), and has been the
basis for the FreeBSD implementation of the tar(1) and cpio(1) utilities
since FreeBSD 5.3.
II. Problem Description
Flaws in libarchive's handling of symlinks and hard links allow overwriting
files outside the extraction directory, or permission changes to a directory
outside the extraction directory.
III. Impact
An attacker who can control freebsd-update's or portsnap's input to tar can
change file content or permisssions on files outside of the update tool's
working sandbox.
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.
No reboot is needed.
Perform one of the following:
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.
This advisory is released concurrently with FreeBSD-SA-16:29.bspatch
which contains special instructions for using freebsd-update. Following
the instructions in that advisory will safely apply updates for
FreeBSD-SA-16:29.bspatch, FreeBSD-SA-16:30.portsnap, and
FreeBSD-SA-16:31.libarchive.
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-16:31/libarchive.patch
