CVE-2020-4355
IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 9.7, 10.1, 10.5, 11.1, and 11.5 is vulnerable to a denial of service, caused by improper handling of Secure Sockets Layer (SSL) renegotiation requests.
Does this matter?
Lower severity and a low EPSS score (2.16%). Track it; it rarely justifies an emergency change on its own.
