F5 Big-ip Webaccelerator 11.5.3

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, WebAccelerator and WebSafe software version 13.0.0, 12.0.0 - 12.1.2, 11.6.0 - 11.6.1 and 11.5.0 - 11.5.4, in some circumstances, Traffic Management Microkernel (TMM) does not properly handle certain malformed TLS1.2 records, which allows remote attackers to cause a denial-of-service (DoS) or possible remote command execution on the BIG-IP system.

In F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, GTM, Link Controller, PEM, WebAccelerator software version 12.0.0 - 12.1.2, 11.6.0 - 11.6.1, 11.4.0 - 11.5.4, 11.2.1, when ConfigSync is configured, attackers on adjacent networks may be able to bypass the TLS protections usually used to encrypted and authenticate connections to mcpd. This vulnerability may allow remote attackers to cause a denial-of-service (DoS) attack via resource exhaustion.
