sol16123: OpenSSL vulnerability CVE-2014-3571
Security Advisory
Original Publication Date: 02/11/2015
Description
OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows
remote attackers to cause a denial of service (NULL pointer dereference and
application crash) via a crafted DTLS message that is processed with a
different read operation for the handshake header than for the handshake body,
related to the dtls1_get_record function in d1_pkt.c and the ssl3_read_n
function in s3_pkt.c. (CVE-2014-3571)
Impact
Remote attackers may be able to cause a denial-of-service (DoS) (NULL pointer
dereference and application crash) by way of a crafted DTLS message.
Status
F5 Product Development has assigned ID 500088 (BIG-IP) to this vulnerability,
and has evaluated the currently supported releases for potential
vulnerability.

*The SOD process is only vulnerable if the failover.secure db variable is
enabled; the db variable is disabled by default.
Recommended Action
If the previous table lists a version in the Versions known to be not
vulnerable column, you can eliminate this vulnerability by upgrading to the
listed version. If the listed version is older than the version you are
currently running, or if the table does not list any version in the column,
then no upgrade candidate currently exists.
F5 is responding to this vulnerability as determined by the parameters defined
in SOL4602: Overview of the F5 security vulnerability response policy.
To mitigate this vulnerability for the BIG-IP system, you can perform the
following tasks:
Verify that DTLS virtual servers referencing SSL profiles do not permit
COMPAT SSL ciphers. If you are using secure-mode for failover (tmsh list /sys
db failover.secure), verify that the failover traffic is only allowed on an
isolated VLAN.
To mitigate this vulnerability for Traffix-SDC, you can perform the following
tasks:
Install the upgrade package that contains openssl-1.0.1e-30.
