Features in F5 BIG-IP 13.0.0-13.1.0.3, 12.1.0-12.1.3.1, 11.6.1-11.6.3.1, 11.5.1-11.5.5, or 11.2.1 system that utilizes inflate functionality directly, via an iRule, or via the inflate code from PEM module are subjected to a service disruption via a "Zip Bomb" attack.
X509 certificate verification was not correctly implemented in the IP Intelligence Subscription and IP Intelligence feed-list features, and thus the remote server's identity is not properly validated in F5 BIG-IP 12.0.0-12.1.2, 11.6.0-11.6.2, or 11.5.0-11.5.5.
Responses to SOCKS proxy requests made through F5 BIG-IP version 13.0.0, 12.0.0-12.1.3.1, 11.6.1-11.6.2, or 11.5.1-11.5.5 may cause a disruption of services provided by TMM. The data plane is impacted and exposed only when a SOCKS proxy profile is attached to a Virtual Server. The control plane is not impacted by this vulnerability.
On F5 BIG-IP 13.0.0, 12.0.0-12.1.3.1, 11.6.0-11.6.2, 11.4.1-11.5.5, or 11.2.1, malformed SPDY or HTTP/2 requests may result in a disruption of service to TMM. Data plane is only exposed when a SPDY or HTTP/2 profile is attached to a virtual server. There is no control plane exposure.
When the F5 BIG-IP 12.1.0-12.1.1, 11.6.0-11.6.1, 11.5.1-11.5.5, or 11.2.1 system is configured with a wildcard IPSec tunnel endpoint, it may allow a remote attacker to disrupt or impersonate the tunnels that have completed phase 1 IPSec negotiations. The attacker must possess the necessary credentials to negotiate the phase 1 of the IPSec exchange to exploit this vulnerability; in many environment this limits the attack surface to other endpoints under the same administration.
In F5 BIG-IP 12.0.0-12.1.2, 11.6.0-11.6.1, 11.5.1-11.5.5, or 11.2.1 there is a vulnerability in TMM related to handling of invalid IP addresses.
Under certain conditions for F5 BIG-IP systems 13.0.0 or 12.1.0 - 12.1.3.1, using FastL4 profiles, when the Reassemble IP Fragments option is disabled (default), some specific large fragmented packets may restart the Traffic Management Microkernel (TMM).
On F5 BIG-IP systems running 13.0.0, 12.1.0 - 12.1.3.1, or 11.6.1 - 11.6.2, the BIG-IP ASM bd daemon may core dump memory under some circumstances when processing undisclosed types of data on systems with 48 or more CPU cores.
In versions 13.0.0, 12.0.0-12.1.3, or 11.6.0-11.6.2, an F5 BIG-IP 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.
X509 certificate verification was not correctly implemented in the early access "user id" feature in the F5 BIG-IP Advanced Firewall Manager versions 13.0.0, 12.1.0-12.1.2, and 11.6.0-11.6.2, and thus did not properly validate the remote server's identity on certain versions of BIG-IP.
In F5 BIG-IP APM software version 13.0.0 and 12.1.2, in some circumstances, APM tunneled VPN flows can cause a VPN/PPP connflow to be prematurely freed or cause TMM to stop responding with a "flow not in use" assertion. An attacker may be able to disrupt traffic or cause the BIG-IP system to fail over to another device in the device group.

Remote client initiating stream beyond the advertised limit can cause a disruption of service. The Traffic Management Microkernel (TMM) data plane is exposed to this issue; the control plane is not exposed.
In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM and Websafe software version 13.0.0, 12.0.0 to 12.1.2 and 11.5.1 to 11.6.1, under limited circumstances connections handled by a Virtual Server with an associated SOCKS profile may not be properly cleaned up, potentially leading to resource starvation. Connections may be left in the connection table which then can only be removed by restarting TMM. Over time this may lead to the BIG-IP being unable to process further connections.
In F5 BIG-IP LTM, AAM, AFM, APM, ASM, Link Controller, PEM, and WebSafe 12.1.0 through 12.1.2, certain values in a TLS abbreviated handshake when using a client SSL profile with the Session Ticket option enabled may cause disruption of service to the Traffic Management Microkernel (TMM). The Session Ticket option is disabled by default.
In F5 BIG-IP PEM 12.1.0 through 12.1.2 when downloading the Type Allocation Code (TAC) database file via HTTPS, the server's certificate is not verified. Attackers in a privileged network position may be able to launch a man-in-the-middle attack against these connections. TAC databases are used in BIG-IP PEM for Device Type and OS (DTOS) and Tethering detection. Customers not using BIG-IP PEM, not configuring downloads of TAC database files, or not using HTTP for that download are not affected.
iControl REST in F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Link Controller, PEM, and WebSafe 12.0.0 through 12.1.2 and 13.0.0 includes a service to convert authorization BIGIPAuthCookie cookies to X-F5-Auth-Token tokens. This service does not properly re-validate cookies when making that conversion, allowing once-valid but now expired cookies to be converted to valid tokens.
In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Link Controller, PEM, and WebSafe 12.1.2-HF1 and 13.0.0, an undisclosed type of responses may cause TMM to restart, causing an interruption of service when "SSL Forward Proxy" setting is enabled in both the Client and Server SSL profiles assigned to a BIG-IP Virtual Server.
In some circumstances, an F5 BIG-IP version 12.0.0 to 12.1.2 and 13.0.0 Azure cloud instance may contain a default administrative password which could be used to remotely log into the BIG-IP system. The impacted administrative account is the Azure instance administrative user that was created at deployment. The root and admin accounts are not vulnerable. An attacker may be able to remotely access the BIG-IP host via SSH.
