On BIG-IP 14.0.0-14.1.0.1, 13.0.0-13.1.1.4, and 12.1.0-12.1.4, internal methods used to prevent arbitrary file overwrites in Appliance Mode were not fully effective. An authenticated attacker with a high privilege level may be able to bypass protections implemented in appliance mode to overwrite arbitrary system files.

On BIG-IP 14.0.0-14.1.0.1, 13.0.0-13.1.1.4, 12.1.0-12.1.4, 11.6.1-11.6.3.4, and 11.5.2-11.5.8, Administrator and Resource Administrator roles might exploit TMSH access to bypass Appliance Mode restrictions on BIG-IP systems.

On BIG-IP 13.0.0-13.1.1.4, 12.1.0-12.1.4, 11.6.1-11.6.3.4, and 11.5.2-11.5.8, SNMP may expose sensitive configuration objects over insecure transmission channels. This issue is exposed when a passphrase is used with various profile types and is accessed using SNMPv2.

When BIG-IP 14.0.0-14.1.0.1, 13.0.0-13.1.1.4, 12.1.0-12.1.4, 11.6.1-11.6.3.4, and 11.5.2-11.5.8 are processing certain rare data sequences occurring in PPTP VPN traffic, the BIG-IP system may execute incorrect logic. The TMM may restart and produce a core file as a result of this condition. The BIG-IP system provisioned with the CGNAT module and configured with a virtual server using a PPTP profile is exposed to this vulnerability.

Platform dependent weakness. This issue only impacts iSeries platforms. On these platforms, in BIG-IP (LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, FPS, GTM, Link Controller, PEM, WebAccelerator) versions 14.0.0-14.1.0.1, 13.0.0-13.1.1.3, and 12.1.1 HF2-12.1.4, the secureKeyCapable attribute was not set which causes secure vault to not use the F5 hardware support to store the unit key. Instead the unit key is stored in plaintext on disk as would be the case for Z100 systems. Additionally this causes the unit key to be stored in UCS files taken on these platforms.

On BIG-IP 11.5.1-11.5.8, 11.6.1-11.6.3, 12.1.0-12.1.3.6, 13.0.0-13.1.1.1, and 14.0.0-14.0.0.2, under certain conditions, hardware systems with a High-Speed Bridge and using non-default Layer 2 forwarding configurations may experience a lockup of the High-Speed Bridge.

In BIG-IP 11.5.1-11.5.8, 11.6.1-11.6.3, 12.1.0-12.1.3, and 13.0.0-13.0.1, malformed TCP packets sent to a self IP address or a FastL4 virtual server may cause an interruption of service. The control plane is not exposed to this issue. This issue impacts the data plane virtual servers and self IPs.

On BIG-IP 11.5.1-11.6.3, 12.1.0-12.1.3, 13.0.0-13.1.1.1, and 14.0.0-14.0.0.2, under certain conditions, the snmpd daemon may leak memory on a multi-blade BIG-IP vCMP guest when processing authorized SNMP requests.

On BIG-IP 11.5.1-11.6.3.4, 12.1.0-12.1.3.7, 13.0.0-13.1.1.3, and 14.0.0-14.0.0.2, when processing certain SNMP requests with a request-id of 0, the snmpd process may leak a small amount of memory.

On BIG-IP 11.5.1-11.5.8, 11.6.1-11.6.3, and 12.0.x, an undisclosed sequence of packets received by an SSL virtual server and processed by an associated Client SSL or Server SSL profile may cause a denial of service.
