Security Advisory Description

The BIG-IP system is vulnerable to a denial of service attack when the MPTCP
option is enabled on a virtual server. Data plane is vulnerable when using the
MPTCP option of a TCP profile. There is no control plane exposure. (
CVE-2017-6159)

Impact

An attacker may be able to disrupt services by causing the Traffic Management
Microkernel (TMM) to restart, hence temporarily failing to process traffic.

^1 The specified products contain the affected code. However, F5 identifies the
vulnerability status as Not vulnerable because the attacker cannot exploit the
code in default, standard, or recommended configurations.

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.

To determine the necessary upgrade path for your BIG-IQ system, you should
understand the BIG-IQ product offering name changes. For more information,

Security Advisory Description

In some cases TMM may crash when processing TCP traffic. (CVE-2017-6162)

Impact

This vulnerability affects the Traffic Management Microkernel (TMM) through a
virtual server configured with TCP profile. Traffic processing is disrupted
while TMM restarts. If the affected BIG-IP system is configured as part of a
device group, it will trigger a failover to the peer device.

Security Advisory Status

F5 Product Development has assigned ID 630475 (BIG-IP) to this vulnerability.

1. The specified products contain the affected code. However, F5 identifies the
vulnerability status as Not vulnerable because the attacker cannot exploit the
code in default, standard, or recommended configurations.

2. The BIG-IP system is also not vulnerable if it meets the following criteria:

  o The BIG-IP system is running any of the following versions:
      - 11.6.0 - 11.6.0 HF4
      - 11.5.0 - 11.5.2 HF1
      - 11.4.0 - 11.4.1 HF3
      - 11.2.1 - 11.2.1 HF10
  o The BIG-IP system has virtual servers that are not associated with TCP
    Analytics profile but associated with TCP profile configured with the
    following settings:
      - Multipath TCP (mptcp) setting is disabled (default)
      - Rate Pace (rate-pace) setting of the Congestion Control section is
        disabled (default)
      - Tail Loss Probe (tail-loss-probe) setting of the Loss Detection and
        Recovery section is disabled (default)
      - Fast Open (fast-open) setting of the Connection Setup section is
        disabled (default)
      - Congestion Metrics Cache Timeout (cmetrics-cache-timeout) setting of
        the Congestion Control section is set to zero (default)
      - Congestion Control (congestion-control) setting of the Congestion
        Control section is set to one of the following:
          - Reno
          - New Reno
          - High Speed (default)
          - Scalable
      - Nagle's Algorithm setting of the Data Transfer section is set to either
        Enabled or Disabled (default)

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.

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, you can enable the Verified Accept setting of
the TCP profile associated with the affected virtual server. To do so, perform
the following procedure:

Impact of action: Performing the following procedure should not have a negative
impact on your system.

 1. Log in to the Configuration utility.
 2. Navigate to Local Traffic > Profiles > Protocol > TCP.
 3. Click on the name of the desired TCP profile.
 4. To enable the setting, select Verified Accept; this setting is disabled by
    default.
 5. To save the change, click Update.
