+FreeBSD-SA-16:33.openssh Security Advisory
+ The FreeBSD Project
+
+Topic: OpenSSH Remote Denial of Service vulnerability
+
+Category: contrib
+Module: OpenSSH
+Announced: 2016-11-02
+Affects: All supported versions of FreeBSD.
+Corrected: 2016-11-02 06:56:35 UTC (stable/11, 11.0-STABLE)
+ 2016-11-02 07:23:19 UTC (releng/11.0, 11.0-RELEASE-p3)
+ 2016-11-02 06:58:47 UTC (stable/10, 10.3-STABLE)
+ 2016-11-02 07:23:36 UTC (releng/10.3, 10.3-RELEASE-p12)
+CVE Name: CVE-2016-8858
+
+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
+
+OpenSSH is an implementation of the SSH protocol suite, providing an
+encrypted and authenticated transport for a variety of services,
+including remote shell access.
+
+During the SSH handshake procedure, the client and server exchanges the
+supported encryption, MAC and compression algorithms along with other
+information to negotiate algorithms for initial key exchange, with a
+message named SSH_MSG_KEXINIT.
+
+II. Problem Description
+
+When processing the SSH_MSG_KEXINIT message, the server could allocate
+up to a few hundreds of megabytes of memory per each connection, before
+any authentication take place.
+
+III. Impact
+
+A remote attacker may be able to cause a SSH server to allocate an excessive
+amount of memory. Note that the default MaxStartups setting on FreeBSD will
+limit the effectiveness of this attack.
+
+IV. Workaround
+
+No workaround is available, but systems where sshd(8) is not used are
+not vulnerable.
+
+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.
+
+The sshd(8) service has to be restarted after the update. A reboot
+is recommended but not required.
+
+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
+
+The sshd(8) service has to be restarted after the update. A reboot
+is recommended but not required.
+
+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-16:33/openssh.patch
+# fetch https://security.FreeBSD.org/patches/SA-16:33/openssh.patch.asc
+# gpg --verify openssh.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>.
+
+The sshd(8) service has to be restarted after the update. A reboot
+is recommended but not required.
+
+VI. Correction details
+
+The following list contains the correction revision numbers for each
+affected branch.

+FreeBSD-SA-16:34.bind Security Advisory
+ The FreeBSD Project
+
+Topic: BIND Remote Denial of Service vulnerability
+
+Category: contrib
+Module: bind
+Announced: 2016-11-02
+Credits: ISC
+Affects: FreeBSD 9.x
+Corrected: 2016-11-02 05:13:27 UTC (stable/9, 9.3-STABLE)
+ 2016-11-02 07:24:34 UTC (releng/9.3, 9.3-RELEASE-p50)
+CVE Name: CVE-2016-8864
+
+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
+
+BIND 9 is an implementation of the Domain Name System (DNS) protocols.
+The named(8) daemon is an Internet Domain Name Server.
+
+II. Problem Description
+
+A defect in BIND's handling of responses containing a DNAME answer could
+cause a resolver to exit after encountering an assertion failure in
+db.c or resolver.c.
+
+During processing of a recursive response that contains a DNAME record
+in the answer section, BIND could stop executing after encountering an
+assertion error in resolver.c.
+
+III. Impact
+
+A remote attacker who could cause a server to make a query deliberately
+chosen to trigger the failed assertions could cause named(8) to stop,
+resulting in a Denial of Service condition to its clients.
+
+IV. Workaround
+
+No workaround is available, but hosts not running named(8) recursive
+servers are not affected.
+
+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.
+
+The named service has to be restarted after the update. A reboot is
+recommended but not required.
+
+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
+
+The named service has to be restarted after the update. A reboot is
+recommended but not required.
+
+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.

+
+b) Apply the patch. Execute the following commands as root:

+# patch < /path/to/patch
+
+c) Recompile the operating system using buildworld and installworld as

+CVE Name: CVE-2016-8610
+
+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
+
+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.
+
+The SSL alert protocol is a way to communicate problems within a SSL/TLS session.
+
+II. Problem Description
+
+Due to improper handling of alert packets, OpenSSL would consume an excessive
+amount of CPU time processing undefined alert messages.
+
+III. Impact
+
+A remote attacker who can initiate handshakes with an OpenSSL based server
+can cause the server to consume a lot of computation power with very little
+bandwidth usage, and may be able to use this technique in a leveraged Denial
+of Service attack.
+
+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.

+
+b) Apply the patch. Execute the following commands as root:
