Summary

F5 BIG-IP versions 14.0.0-14.0.0.2, 13.0.0-13.1.1.5, 12.1.0-12.1.4.1, and 11.2.1-11.6.3.2 contain a vulnerability that allows an attacker to disrupt SSL communication. By sending specially crafted SSL records to an SSL Virtual Server, this vulnerability leads to corruption in SSL data structures. As a result, clients may encounter 'decrypt BAD_RECORD_MAC' errors, preventing access to applications load-balanced by the affected virtual server until the traffic management process (tmm) is restarted.

Affected Version(s)

BIG-IP (LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, FPS, GTM, Link Controller, PEM, WebAccelerator) 14.0.0-14.0.0.2, 13.0.0-13.1.0.7, 12.1.0-12.1.3.5, 11.6.0-11.6.3.2, 11.2.1-11.5.6
