CVE-2018-15319
On BIG-IP 14.0.0-14.0.0.2, 13.0.0-13.1.1.1, or 12.1.0-12.1.3.6, malicious requests made to virtual servers with an HTTP profile can cause the TMM to restart.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.86%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
