For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit <URL:http://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.
II. Problem Description
Receipt of an invalid DTLS fragment on an OpenSSL DTLS client or server can
lead to a buffer overrun. [CVE-2014-0195]
Receipt of an invalid DTLS handshake on an OpenSSL DTLS client can lead the
code to unnecessary recurse. [CVE-2014-0221]
Carefully crafted handshake can force the use of weak keying material in
OpenSSL SSL/TLS clients and servers. [CVE-2014-0224]
Carefully crafted packets can lead to a NULL pointer deference in OpenSSL
TLS client code if anonymous ECDH ciphersuites are enabled. [CVE-2014-3470]
III. Impact
A remote attacker may be able to run arbitrary code on a vulnerable client
or server by sending invalid DTLS fragments to an OpenSSL DTLS client or
server. [CVE-2014-0195]
A remote attacker who can send an invalid DTLS handshake to an OpenSSL DTLS
client can crash the remote OpenSSL DTLS client. [CVE-2014-0221]
A remote attacker who can send a carefully crafted handshake can force the
use of weak keying material between a vulnerable client and a vulnerable
server and decrypt and/or modify traffic from the attacked client and
server in a man-in-the-middle (MITM) attack. [CVE-2014-0224]
A remote attacker who can send carefully crafted packets can cause OpenSSL
TLS client to crash. [CVE-2014-3470]
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.
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.
[FreeBSD 10.0]
# fetch http://security.FreeBSD.org/patches/SA-14:14/openssl-10.patch
# fetch http://security.FreeBSD.org/patches/SA-14:14/openssl-10.patch.asc
# gpg --verify openssl-10.patch.asc
[FreeBSD 9.x and 8.x]
# fetch http://security.FreeBSD.org/patches/SA-14:14/openssl-9.patch
# fetch http://security.FreeBSD.org/patches/SA-14:14/openssl-9.patch.asc
# gpg --verify openssl-9.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:http://www.FreeBSD.org/handbook/makeworld.html>.
Restart all deamons using the library, or reboot the system.
3) 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
VI. Correction details
The following list contains the correction revision numbers for each
affected branch.
Branch/path Revision

Hi, One, my appologies if it's a stupid one, question: the advisory is for DTLS, hence UDP TLS, right? Normally you would run SSL (TLS a.o.) via TCP. So what would use DTLS (in the base system) and could be vulnerable? A mailserver using TLS and linked to the base system's openssl would be using TCP...? Thanks in advance.
