F5: Security Vulnerabilities
The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action.

In F5 BIG-IP APM software versions 11.5.0, 11.5.1, 11.5.2, 11.5.3, 11.5.4, 11.6.0, 11.6.1, 12.0.0, 12.1.0, 12.1.1 and 12.1.2 BIG-IP APM portal access requests do not return the intended resources in some cases. This may allow access to internal BIG-IP APM resources, however the application resources and backend servers are unaffected.

A SQL injection vulnerability exists in the BIG-IP AFM management UI on versions 12.0.0, 12.1.0, 12.1.1, 12.1.2 and 13.0.0 that may allow a copy of the firewall rules to be tampered with and impact the Configuration Utility until there is a resync of the rules. Traffic processing and the live firewall rules in use are not affected.

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.

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM and WebSafe software version 13.0.0 and 12.1.0 - 12.1.2, malicious requests made to virtual servers with an HTTP profile can cause the TMM to restart. The issue is exposed with BIG-IP APM profiles, regardless of settings. The issue is also exposed with the non-default "normalize URI" configuration options used in iRules and/or BIG-IP LTM policies.
