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
The receipt of a specifically crafted DTLS handshake message may cause OpenSSL
to consume large amounts of memory. [CVE-2014-3506]
The receipt of a specifically crafted DTLS packet could cause OpenSSL to leak
memory. [CVE-2014-3507]
A flaw in OBJ_obj2txt may cause pretty printing functions such as
X509_name_oneline, X509_name_print_ex et al. to leak some information from
the stack. [CVE-2014-3508]
OpenSSL DTLS clients enabling anonymous (EC)DH ciphersuites are subject to
a denial of service attack. [CVE-2014-3510]
The following problems affect FreeBSD 10.0-RELEASE and later:
If a multithreaded client connects to a malicious server using a resumed
session and the server sends an ec point format extension it could write
up to 255 bytes to freed memory. [CVE-2014-3509]
A flaw in the OpenSSL SSL/TLS server code causes the server to negotiate
TLS 1.0 instead of higher protocol versions when the ClientHello message
is badly fragmented. [CVE-2014-3511]
A malicious client or server can send invalid SRP parameters and overrun
an internal buffer. [CVE-2014-3512]
A malicious server can crash the client with a NULL pointer dereference by
specifying a SRP ciphersuite even though it was not properly negotiated
with the client. [CVE-2014-5139]
III. Impact
A remote attacker may be able to cause a denial of service (application
crash, large memory consumption), obtain additional information,
cause protocol downgrade. Additionally, a remote attacker may be able
to run arbitrary code on a vulnerable system if the application has been
set up for SRP.
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-14:18/openssl-10.0.patch
# fetch http://security.FreeBSD.org/patches/SA-14:18/openssl-10.0.patch.asc
# gpg --verify openssl-10.0.patch.asc
[FreeBSD 9.3]
# fetch http://security.FreeBSD.org/patches/SA-14:18/openssl-9.3.patch
# fetch http://security.FreeBSD.org/patches/SA-14:18/openssl-9.3.patch.asc
# gpg --verify openssl-9.3.patch.asc
[FreeBSD 9.2, 9.1, 8.4]
# fetch http://security.FreeBSD.org/patches/SA-14:18/openssl-9.patch
# fetch http://security.FreeBSD.org/patches/SA-14:18/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.
