K31404801: F5 BIG-IP TMM vulnerability CVE-2017-6169
Security Advisory Description
A virtual server using the URL categorization feature may cause the Traffic
Management Microkernel (TMM) to produce a core file when it receives malformed
URLs during categorization. (CVE-2017-6169).
Impact
An attacker may be able to disrupt traffic or cause the BIG-IP system to fail
over to another device in the device group.
This vulnerability affects BIG-IP systems with the following configuration:
The BIG-IP system has Policy Enforcement Manager (PEM) provisioned.
The URL categorization feature is licensed on the system.
One or more virtual servers use URL categorization through one of the following:
An iRule
A Centralized Policy Matching (CPM) rule.
A BIG-IP PEM policy.
One or more virtual servers process malformed URL categorization input.
Note: The URL categorization feature enables you to enforce policies configured
as part of the subscriber profile based on the URL category type; the URL
categorization is obtained by querying an internal repository.

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 Fixes introduced in 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.
Note: For details about how Security Advisory articles are versioned, and what
versions are listed in the table, refer to K51812227: Understanding Security
Advisory versioning.
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.
