CVE-2020-4200
IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 10.5, 11.1, and 11.5 could allow an authenticated attacker to send specially crafted commands to cause a denial of service.
Does this matter?
Lower severity and a low EPSS score (1.64%). Track it; it rarely justifies an emergency change on its own.
