CVE-2016-9589
Undertow in Red Hat wildfly before version 11.0.0.Beta1 is vulnerable to a resource exhaustion resulting in a denial of service.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.96%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
