An Information Disclosure vulnerability exists in NTP 4.2.7p25 private (mode 6/7) messages via a GET_RESTRICT control message, which could let a malicious user obtain sensitive information.

On F5 BIG-IP 12.1.0-12.1.3.1, 11.6.1-11.6.3.1, 11.5.1-11.5.5, or 11.2.1, carefully crafted URLs can be used to reflect arbitrary content into GeoIP lookup responses, potentially exposing clients to XSS.

On F5 BIG-IP 13.0.0, 12.0.0-12.1.2, 11.6.1-11.6.3.1, 11.5.1-11.5.5, or 11.2.1, when processing DIAMETER transactions with carefully crafted attribute-value pairs, TMM may crash.

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 13.0.0, 12.1.0-12.1.2, 11.6.1, 11.5.1-11.5.5, or 11.2.1 the Apache modules apache_auth_token_mod and mod_auth_f5_auth_token.cpp allow possible unauthenticated bruteforce on the em_server_ip authorization parameter to obtain which SSL client certificates used for mutual authentication between BIG-IQ or Enterprise Manager (EM) and managed BIG-IP devices.

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.

In some circumstances, on F5 BIG-IP systems running 13.0.0, 12.1.0 - 12.1.3.1, any 11.6.x or 11.5.x release, or 11.2.1, TCP DNS profile allows excessive buffering due to lack of flow control.

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, Websafe software version 12.0.0 to 12.1.2, 11.6.0 to 11.6.1, 11.4.0 to 11.5.4, 11.2.1, in some cases TMM may crash when processing TCP traffic. This vulnerability affects TMM via a virtual server configured with TCP profile. Traffic processing is disrupted while Traffic Management Microkernel (TMM) restarts. If the affected BIG-IP system is configured to be part of a device group, it will trigger a failover to the peer device.

A stored cross-site scripting (XSS) vulnerability in the Configuration utility device name change page in BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, PSM, WebAccelerator, WOM and WebSafe version 12.0.0 - 12.1.2, 11.4.0 - 11.6.1, and 11.2.1 allows an authenticated user to inject arbitrary web script or HTML. Exploitation requires Resource Administrator or Administrator privileges, and it could cause the Configuration utility client to become unstable.
