K48042976 : BIG-IP SSL vulnerability CVE-2016-4545

Security Advisory Description

On virtual servers with Secure Sockets Layer (SSL) profiles enabled, an SSL alert sent during the handshake may produce unnecessary logging and resource consumption on a BIG-IP system that is running 11.5.4 FINAL, possibly causing the Traffic Management Microkernel (TMM) to restart and produce a core file. (CVE-2016-4545)
Impact
When a Secure Sockets Layer (SSL) alert is sent during the handshake on a BIG-IP 11.5.4 base, the TMM may restart and produce a core file while logging SSL ‘codec alert’ messages to the /var/log/ltm file. The messages appear similar to the following example:
warning tmm[32354]: 01260009:4: Connection error: hud_ssl_handler:1131: codec alert (20)
