Security Advisory Description

Untrusted search path vulnerability in ssh-agent.c in ssh-agent in OpenSSH
before 7.4 allows remote attackers to execute arbitrary local PKCS#11 modules
by leveraging control over a forwarded agent-socket. (CVE-2016-10009)

Impact

Running the ssh-agent program requires a local administrator to connect to the
system and run the command. Once the ssh-agent has been started, an attacker
could run code on the system that is running the ssh-agent if the attacker has
control of the forwarded agent socket on the host running the sshd server and
can write to the filesystem of the host that is running the ssh-agent.

Security Advisory Status

F5 Product Development has assigned ID 636453 (BIG-IP, iWorkflow, BIG-IQ, and
Enterprise Manager), and INSTALLER-2868 (Traffix SDC) to this vulnerability.
Additionally, BIG-IP iHealth may list Heuristic H31440025 on the Diagnostics >
Identified > Medium screen.

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.

Mitigation

F5 advises that you do not use the ssh-agent program on F5 products.

K64292204: OpenSSH vulnerability CVE-2016-10010

Security Advisory Original Publication Date: Jan 24, 2017 

Updated Date: Jan 24, 2017

Applies to (see versions): 

Vulnerability Description

sshd in OpenSSH before 7.4, when privilege separation is not used, creates 
forwarded Unix-domain sockets as root, which might allow local users to gain 
privileges via  unspecified vectors, related to serverloop.c.
(CVE-2016-10010)

Impact

In the default configuration, there is no impact. However, if the 
administrator disables privilege separation in the system sshd_config file, 
the system can be exposed to this vulnerability.

Security Issue Status F5 Product Development has assigned ID 636460 (BIG-IP, 
iWorkflow, BIG-IQ, Enterprise Manager), and ID INSTALLER-2868 (Traffix SDC) to
this vulnerability.

To determine if your release is known to be vulnerable, the components or 
features that are affected by the vulnerability, and for information about

Vulnerability Recommended Actions If you are running a version listed in the 
Versions known to be vulnerable column, you can eliminate this vulnerability 
by upgrading to a version listed in the Versions known to be not vulnerable 
column. If the table lists only an older version than what you are currently 
running, or does not list a non-vulnerable version, then no upgrade candidate
currently exists.

To determine the necessary upgrade path for your BIG-IQ system, you should 
understand the BIG-IQ product offering name changes. For more information, 
refer to K21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow 
systems.

Mitigation

To mitigate this vulnerability for BIG-IP products, F5 recommends that you 
re-enable privilege separate, if you have disabled it. To do so, perform the 
following procedure:

Impact of action: Improper modifications to the SSH configuration can prevent
SSH login. You should perform changes from the serial console.

Log in to the Traffic Management Shell (tmsh) by typing the following command:
tmsh

To determine if you have privilege separation disabled, type the following 
command: list /sys sshd

If you observe the following command output, then privilege separation is 
disabled, and you should proceed to step 3.

sys sshd { include "UsePrivilegeSeparation no" }

If there is no command output, or you do not see the UsePrivilegeSeparation no
include statement in the output, then privilege separation is enabled and you
do not need to proceed.

Note: For more information regarding the UsePrivilegeSeparation option, refer
to the manual page for sshd_config, by typing the following command from the 
Bash prompt (not the tmsh utility):

man sshd_config

To re-enable privilege separation, remove the custom include statement by 
typing the following command: edit /sys sshd

If there are multiple include statements, locate the UsePrivilegeSeparation no
line, and remove just that statement. If UsePrivilegeSeparation no is the only
include statement, replace that statement with the word none. For example:

modify sshd { include none }

Save your changes for the sshd configuration, and exit the vi editor. To save
the configuration, type the following command: save /sys config

To exit the tmsh utility, type q and press Enter. Note: You do not need to 
restart the sshd service; the new changes are active once you save the 
configuration.
